{"schema":"threatline.record/2","record":{"id":"CVE-2026-86035","aliases":["GHSA-327h-qqgm-qv55"],"summary":"Weblate: Mercurial argument injection via repository filenames allows authenticated command execution","details":"Weblate is a web-based continuous localization platform used to manage software translations. Weblate 4.11.1 through 2026.7.1 contains an argument-injection vulnerability in its Mercurial backend. Repository filenames beginning with - could be interpreted as Mercurial options instead of literal paths. An authenticated user with project-scoped component.edit permission could exploit this through a Mercurial-backed RESX component using the Update RESX files add-on. A later repository update could execute arbitrary commands with the privileges of the Weblate service account. This is a residual incomplete fix for CVE-2022-23915. This issue has been patched in version 2026.8.","categories":["Unclassified"],"product":"weblate","vendor":"WeblateOrg","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86035","source_modified_at":"2026-10-02T12:09:21.053Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"weblate","vendor":"WeblateOrg","versions":[{"status":"affected","version":">= 4.11.1, < 2026.8"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-327h-qqgm-qv55","source_modified_at":"2026-09-04T19:34:08Z","fetched_at":"2026-10-23T21:10:45.942435Z","package":{"ecosystem":"pip","name":"Weblate"},"range":"<2026.8,>4.11.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-327h-qqgm-qv55","source_modified_at":"2026-09-04T19:34:08Z","fetched_at":"2026-10-23T21:10:45.942435Z","package":{"ecosystem":"pip","name":"Weblate"},"version":"2026.8"}],"cvss":8.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00366,"percentile":0.29331,"score_date":"2026-10-23"},"published_at":"2026-09-29T14:58:20.313Z","modified_at":"2026-10-02T12:09:21.053Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-86035","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-02T12:09:21.053Z"},{"source":"GitHub Advisory Database","url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-327h-qqgm-qv55","fetched_at":"2026-10-23T21:10:45.942435Z","source_modified_at":"2026-09-04T19:34:08Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-86035","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-327h-qqgm-qv55","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/WeblateOrg/weblate/pull/20768","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/WeblateOrg/weblate/commit/f60a9759a6d851bd10ccdefe9b1b7f0cdb9e9bbd","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/WeblateOrg/weblate/releases/tag/weblate-2026.8","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-02T12:09:07.392381Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-02T12:09:21.053Z","content_hash":"dfed284c881ebe77b0bce4b79bbeef11ce469b26fcfc3d9fb4afe4834549cdfa"}}
