{"schema":"threatline.record/2","record":{"id":"CVE-2026-115932","aliases":[],"summary":"Path traversal in post media lets any registered user read server files","details":"When a post is published, Postiz treats a media path that is not a web address as a file on the server's disk, but it does not check that the file lies inside the upload directory. A registered user can store a crafted media path with a post, get it past the checks that normally restrict it, and have the publishing worker read an arbitrary file and send it as an attachment to a Discord server the user controls.\n\nThe same unconfined reads can be reached through two further routes. One tells the caller whether a file exists and can exhaust the backend's memory, the other delivers the file the same way as the main route. Self-registration is open by default, so the attacker needs no existing account.","categories":["Unclassified"],"product":"postiz-app","vendor":"GitroomHQ","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115932","source_modified_at":"2026-10-24T14:18:20.861Z","fetched_at":"2026-10-24T14:26:37.433577Z","product":"postiz-app","vendor":"GitroomHQ","versions":[{"version":"2.23.0","status":"affected","versionType":"semver","lessThan":"2.25.3"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115932","source_modified_at":"2026-10-24T14:18:20.861Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"name":"postiz-app","ecosystem":null},"version":"2.25.3","basis":"first unaffected version stated in the CVE record"}],"cvss":9.6,"severity":"Critical","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-24T12:28:36.033Z","modified_at":"2026-10-24T14:18:20.861Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115932","fetched_at":"2026-10-24T14:26:37.433577Z","source_modified_at":"2026-10-24T14:18:20.861Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/gitroomhq/postiz-app","tags":["product"]},{"source":"CVE List","url":"https://github.com/gitroomhq/postiz-app/releases/tag/v2.25.3","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/gitroomhq/postiz-app/commit/12db9bd2f428b628a62809669c3d76297e07750a","tags":["patch"]},{"source":"CVE List","url":"https://gadvisory.org/advisories/PSA-2026-E9AHFV","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-24T14:18:20.861Z","content_hash":"3ae3984ca773de50aef4940bb0d10dcfc2ab991dd24601400a5bc0aff349d6b6"}}
