If an operator unintentionally carried that setting into an environment where plugin paths are writable by less-trusted users, unsigned plugin code could be loaded.\n\n### Patches\nPatched in 0.9.0a2. Disabling plugin signature enforcement now requires a second explicit acknowledgment value.\n\n### Workarounds\nBefore upgrading, keep plugin signing required in all shared or production environments and ensure plugin directories are not writable by untrusted users.\n\n### Upgrade\nUpgrade to the patched release:\n\n```bash\npip install --upgrade --pre stigmem-node\n```\n\nIf developers install through the Stigmem meta-package instead, they should use the matching extra for deployments, for example:\n\n```bash\npip install --upgrade --pre 'stigmem[node]'\n```\n\n### Resources\n- Release: https://github.com/eidetic-labs/stigmem/releases/tag/v0.9.0a2\n- Changelog: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/CHANGELOG.md#L14-L35\n- Security policy and posture: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/SECURITY.md","published":"2026-08-19T14:02:18.743Z","modified":"2026-09-13T03:30:28.541415069Z","cvss":null,"epss":{"score":0.00088,"percentile":0.00443,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"stigmem-node","fixedVersion":"0.9.0a2"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76241.json"},{"type":"ADVISORY","url":"https://github.com/eidetic-labs/stigmem/security/advisories/GHSA-w7pm-9g55-mxfm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76241"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/stigmem-plugin-signature-enforcement-bypass-via-configuration"},{"type":"PACKAGE","url":"https://github.com/eidetic-labs/stigmem"},{"type":"WEB","url":"https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/CHANGELOG.md#L14-L35"},{"type":"WEB","url":"https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/SECURITY.md"},{"type":"WEB","url":"https://github.com/eidetic-labs/stigmem/releases/tag/v0.9.0a2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-13T03:30:28.541415069Z"}}
