Warning

Some dependencies could not be looked up. Check the Dependency Dashboard for more information.

Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function

CVE-2026-25645 / GHSA-gc5v-m9x4-r6x2 / PYSEC-2026-2275

More information

Details

Impact

The requests.utils.extract_zipped_paths() utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one.

Affected usages

Standard usage of the Requests library is not affected by this vulnerability. Only applications that call extract_zipped_paths() directly are impacted.

Remediation

Upgrade to at least Requests 2.33.0, where the library now extracts files to a non-deterministic location.

If developers are unable to upgrade, they can set TMPDIR in their environment to a directory with restricted write access.

Severity

  • CVSS Score: 4.4 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:N

CVE-2026-25645 / GHSA-gc5v-m9x4-r6x2 / PYSEC-2026-2275

More information

Details

Requests is a HTTP library. Prior to version 2.33.0, the requests.utils.extract_zipped_paths() utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call extract_zipped_paths() directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set TMPDIR in their environment to a directory with restricted write access.

Severity

  • CVSS Score: 5.5 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N

Announcements

  • 📣 Requests is adding inline types. If you have a typed code base that
    uses Requests, please take a look at #​7271. Give it a try, and report
    any gaps or feedback you may have in the issue. 📣

Security

  • CVE-2026-25645 requests.utils.extract_zipped_paths now extracts
    contents to a non-deterministic location to prevent malicious file
    replacement. This does not affect default usage of Requests, only
    applications calling the utility function directly.

Improvements

  • Migrated to a PEP 517 build system using setuptools. (#​7012)

Bugfixes

  • Fixed an issue where an empty netrc entry could cause
    malformed authentication to be applied to Requests on
    Python 3.11+. (#​7205)

Deprecations

  • Dropped support for Python 3.9 following its end of support. (#​7196)

Documentation

  • Various typo fixes and doc improvements.

EPSS Score0.765%
EPSS Percentile51st percentile
Description

During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake.

Description

Impact

What kind of vulnerability is it? Who is impacted?

It is an Authorization Bypass resulting from Improper Input Validation of the HTTP/2 :path pseudo-header.

The gRPC-Go server was too lenient in its routing logic, accepting requests where the :path omitted the mandatory leading slash (e.g., Service/Method instead of /Service/Method). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official grpc/authz package) evaluated the raw, non-canonical path string. Consequently, "deny" rules defined using canonical paths (starting with /) failed to match the incoming request, allowing it to bypass the policy if a fallback "allow" rule was present.

Who is impacted?
This affects gRPC-Go servers that meet both of the following criteria:

  1. They use path-based authorization interceptors, such as the official RBAC implementation in google.golang.org/grpc/authz or custom interceptors relying on info.FullMethod or grpc.Method(ctx).
  2. Their security policy contains specific "deny" rules for canonical paths but allows other requests by default (a fallback "allow" rule).

The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed :path headers directly to the gRPC server.

Patches

Has the problem been patched? What versions should users upgrade to?

Yes, the issue has been patched. The fix ensures that any request with a :path that does not start with a leading slash is immediately rejected with a codes.Unimplemented error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string.

Users should upgrade to the following versions (or newer):

  • v1.79.3
  • The latest master branch.

It is recommended that all users employing path-based authorization (especially grpc/authz) upgrade as soon as the patch is available in a tagged release.

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods:

1. Use a Validating Interceptor (Recommended Mitigation)

Add an "outermost" interceptor to your server that validates the path before any other authorization logic runs:

func pathValidationInterceptor(ctx context.Context, req any, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (any, error) {
    if info.FullMethod == "" || info.FullMethod[0] != '/' {
        return nil, status.Errorf(codes.Unimplemented, "malformed method name")
    }   
    return handler(ctx, req)
}

// Ensure this is the FIRST interceptor in your chain
s := grpc.NewServer(
    grpc.ChainUnaryInterceptor(pathValidationInterceptor, authzInterceptor),
)

2. Infrastructure-Level Normalization

If your gRPC server is behind a reverse proxy or load balancer (such as Envoy, NGINX, or an L7 Cloud Load Balancer), ensure it is configured to enforce strict HTTP/2 compliance for pseudo-headers and reject or normalize requests where the :path header does not start with a leading slash.

3. Policy Hardening

Switch to a "default deny" posture in your authorization policies (explicitly listing all allowed paths and denying everything else) to reduce the risk of bypasses via malformed inputs.

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root.

The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.

Description

ReverseProxy can forward queries containing parameters not visible to Rewrite functions.

When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not take ParseQuery's limit on the total number of query parameters (controlled by GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a query parameter that is not visible to the Rewrite function.

For example, the query "a1=x&a2=x&...&a10000=x&hidden=y" can forward the parameter "hidden=y" while hiding it from the proxy's Rewrite function.

Description

Impact

The HAProxy PROXY protocol v2 codec in netty leaks native or heap memory on every connection when a client sends a syntactically valid header containing nested PP2_TYPE_SSL TLVs (type-length-value records) at depth two or greater. The leak occurs on the successful parse path — no exception is thrown, the message fires downstream, the decoder removes itself, and the application releases the HAProxyMessage normally. Yet the underlying cumulation buffer (a pooled, potentially direct ByteBuf allocated by the channel) remains permanently pinned.

When decoding a PP2_TYPE_SSL TLV, HAProxyMessage.readNextTLV() first calls header.retainedSlice(header.readerIndex(), length) and only then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5, the subsequent readByte/readInt throws IndexOutOfBoundsException. HAProxyMessageDecoder only catches HAProxyProtocolException around this call, so the IOOBE propagates and the retained slice on the pooled cumulation buffer is never released.

Summary

The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.

Root Cause

sdk/resource/host_id.go line 42:

if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {

Compare with the fixed Darwin path at line 58:

result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")

The execCommand helper at sdk/resource/host_id_exec.go uses exec.Command(name, arg...) which searches $PATH when the command name contains no path separator.

Affected platforms (per build tag in host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.

The kenv path is reached when /etc/hostid does not exist (line 38-40), which is common on FreeBSD systems.

Attack

  1. Attacker has local access to a system running a Go application that imports go.opentelemetry.io/otel/sdk
  2. Attacker places a malicious kenv binary earlier in $PATH
  3. Application initializes OpenTelemetry resource detection at startup
  4. hostIDReaderBSD.read() calls exec.Command("kenv", ...) which resolves to the malicious binary
  5. Arbitrary code executes in the context of the application

Same attack vector and impact as CVE-2026-24051.

Suggested Fix

Use the absolute path:

if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); err == nil {

On FreeBSD, kenv is located at /bin/kenv.

Description

multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. this allows an attacker to amplify cpu and allocations by sending many baggage: header lines, even when each individual value is within the 8192-byte per-value parse limit.

severity

HIGH (availability / remote request amplification)

relevant links

vulnerability details

pins: open-telemetry/opentelemetry-go@1ee4a41
as-of: 2026-02-04
policy: direct (no program scope provided)

callsite: propagation/baggage.go:58 (extractMultiBaggage)
attacker control: inbound HTTP request headers (many baggage field-values) → propagation.HeaderCarrier.Values("baggage") → repeated baggage.Parse + member aggregation

root cause

extractMultiBaggage iterates over all baggage header field-values and parses each one independently, then appends members into a shared slice. the 8192-byte parsing cap applies per header value, but the multi-value path repeats that work once per header line (bounded only by the server/proxy header byte limit).

impact

in a default net/http configuration (max header bytes 1mb), a single request with many baggage: header field-values can cause large per-request allocations and increased latency.

example from the attached PoC harness (darwin/arm64; 80 values; 40 requests):

  • canonical: per_req_alloc_bytes=10315458 and p95_ms=7
  • control: per_req_alloc_bytes=133429 and p95_ms=0

proof of concept

canonical:

mkdir -p poc
unzip poc.zip -d poc
cd poc
make test

output (excerpt):

[CALLSITE_HIT]: propagation/baggage.go:58 extractMultiBaggage
[PROOF_MARKER]: baggage_multi_value_amplification p95_ms=7 per_req_alloc_bytes=10315458 per_req_allocs=16165

control:

cd poc
make control

control output (excerpt):

[NC_MARKER]: baggage_single_value_baseline p95_ms=0 per_req_alloc_bytes=133429 per_req_allocs=480

expected: multiple baggage header field-values should be semantically equivalent to a single comma-joined baggage value and should not multiply parsing/alloc work within the effective header byte budget.
actual: multiple baggage header field-values trigger repeated parsing and member aggregation, causing high per-request allocations and increased latency even when each individual value is within 8192 bytes.

fix recommendation

avoid repeated parsing across multi-values by enforcing a global budget and/or normalizing multi-values into a single value before parsing. one mitigation approach is to treat multi-values as a single comma-joined string and cap total parsed bytes (for example 8192 bytes total).

fix accepted when: under the default PoC harness settings, canonical stays within 2x of control for per_req_alloc_bytes and per_req_allocs, and p95_ms stays below 2ms.
