Prior to 1.13.0, Arcane has a command injection in the updater service. Arcane\u2019s updater service supported lifecycle labels com.getarcaneapp.arcane.lifecycle.pre-update and com.getarcaneapp.arcane.lifecycle.post-update that allowed defining a command to run before or after a container update. The label value is passed directly to /bin/sh -c without sanitization or validation. Because any authenticated user (not limited to administrators) can create projects through the API, an attacker can create a project that specifies one of these lifecycle labels with a malicious command. When an administrator later triggers a container update (either manually or via scheduled update checks), Arcane reads the lifecycle label and executes its value as a shell command inside the container. This vulnerability is fixed in 1.13.0."}], "lastModified": "2026-02-05T21:37:01.000", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:arcane:arcane:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C6334A63-DF55-490B-9840-4805617B2E8D", "versionEndExcluding": "1.13.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
