{"schema":"threatline.record/2","record":{"id":"CVE-2026-58255","aliases":["GHSA-9xpg-9w3g-mpwj"],"summary":"Cronicle: Non-admin uid/gid injection in create_event/update_event → run-as-arbitrary-user (incl. root) — sibling of CVE-2026-39401","details":"Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.121, a non-administrator user or scoped API key with `create_events` and `run_events` privileges can inject top-level `uid` and `gid` fields through `/api/app/create_event` or `/api/app/update_event`. In `lib/api.js`, `requireValidEventData` uses `validateOptionalParams` as a partial allow-list that silently passes unknown keys, storing the injected fields verbatim. In `lib/job.js`, `launchJob` copies the whole event into the job, and a plugin `uid` overrides the event `uid` only when the plugin defines one. The default `shellplug` and `urlplug` plugins do not define a `uid`, so the event-controlled identity survives into child-process launch. On a root-daemon installation, this lets a low-privileged user run jobs as arbitrary users, including root, bypassing the otherwise administrator-only run-as-user control. This API-side event injection is distinct from the job-output `uid`/`gid` injection addressed by CVE-2026-39401. This issue is fixed in version 0.9.121.","categories":["Unclassified"],"product":"Cronicle","vendor":"jhuckaby","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-58255","source_modified_at":"2026-10-28T16:12:46.274Z","fetched_at":"2026-10-28T20:58:01.013507Z","product":"Cronicle","vendor":"jhuckaby","versions":[{"version":"< 0.9.121","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00415,"percentile":0.35681,"score_date":"2026-10-28"},"published_at":"2026-10-27T22:30:09.563Z","modified_at":"2026-10-28T16:12:46.274Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-58255","fetched_at":"2026-10-28T20:58:01.013507Z","source_modified_at":"2026-10-28T16:12:46.274Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-58255","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/jhuckaby/Cronicle/security/advisories/GHSA-9xpg-9w3g-mpwj","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/jhuckaby/Cronicle/commit/f3d3550d0f3fe89bab52d3788f0db1dd10860df2","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/jhuckaby/Cronicle/releases/tag/v0.9.121","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":"2026-10-28T14:58:21.748464Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T16:12:46.274Z","content_hash":"b2ceca08f27c19eb7d1ed8d073aa67a6e2ace008adaf316a188b0a13b282670d"}}
