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.","state":0,"publishedAt":"2026-10-27T22:30:09.563+00:00","modifiedAt":"2026-10-28T16:12:46.274+00:00","affected":[{"ecosystem":"Vendor product","name":"Cronicle","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"jhuckaby\",\n                    \"product\": \"Cronicle\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.9.121\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/jhuckaby/Cronicle/security/advisories/GHSA-9xpg-9w3g-mpwj","https://github.com/jhuckaby/Cronicle/commit/f3d3550d0f3fe89bab52d3788f0db1dd10860df2","https://github.com/jhuckaby/Cronicle/releases/tag/v0.9.121"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-58255","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-58255","identifiers":["CVE-2026-58255"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
