Summary
stigmem-node's federation peer token timestamp validation may reject valid peer tokens
Workarounds
Before upgrading, avoid mixed peer-token minting paths and restrict federation use to tightly controlled peers.
Upgrade
Upgrade to the patched release:
pip install --upgrade --pre stigmem-node
If developers install through the Stigmem meta-package instead, they should use the matching extra for deployments, for example:
pip install --upgrade --pre 'stigmem[node]'

- Release: https://github.com/eidetic-labs/stigmem/releases/tag/v0.9.0a2
- Changelog: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/CHANGELOG.md#L14-L35
- Security policy and posture: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/SECURITY.md
Impact
A mismatch in federation peer-token timestamp handling could cause valid peer tokens to be treated as expired. Impacted deployments are Stigmem nodes using federation peer authentication paths from affected versions. The primary impact is availability and reliability of authenticated federation flows.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Patched in 0.9.0a2. Federation peer-token timestamp handling now uses the canonical millisecond-based validation path and is covered by regression tests.
Frequently Asked Questions
- What is GHSA-XH5J-XJFQ-QVVX? GHSA-XH5J-XJFQ-QVVX is a high-severity security vulnerability in stigmem-node (pip), affecting versions < 0.9.0a2. It is fixed in 0.9.0a2.
- Which versions of stigmem-node are affected by GHSA-XH5J-XJFQ-QVVX? stigmem-node (pip) versions < 0.9.0a2 is affected.
- Is there a fix for GHSA-XH5J-XJFQ-QVVX? Yes. GHSA-XH5J-XJFQ-QVVX is fixed in 0.9.0a2. Upgrade to this version or later.
- Is GHSA-XH5J-XJFQ-QVVX exploitable, and should I be worried? Whether GHSA-XH5J-XJFQ-QVVX is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-XH5J-XJFQ-QVVX is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
