{"id":"CVE-2026-115932","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.","modified":"2026-10-25T02:46:14.513969005Z","published":"2026-10-24T12:28:36.033Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115932.json","unresolved_ranges":[{"extracted_events":[{"range":[{"introduced":"2.23.0"},{"fixed":"2.25.3"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}],"cna_assigner":"postiz","cwe_ids":["CWE-22","CWE-74"]},"references":[{"type":"ADVISORY","url":"https://gadvisory.org/advisories/PSA-2026-E9AHFV"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115932.json"},{"type":"PACKAGE","url":"https://github.com/gitroomhq/postiz-app"},{"type":"FIX","url":"https://github.com/gitroomhq/postiz-app/commit/12db9bd2f428b628a62809669c3d76297e07750a"},{"type":"ADVISORY","url":"https://github.com/gitroomhq/postiz-app/releases/tag/v2.25.3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115932"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gitroomhq/postiz-app","events":[{"introduced":"0"},{"fixed":"a5affe62c74e39c1e7ac960d50d8418b807d532c"},{"fixed":"12db9bd2f428b628a62809669c3d76297e07750a"}],"database_specific":{"extracted_events":[{"original_tag":"v2.25.3","range":[{"fixed":"a5affe62c74e39c1e7ac960d50d8418b807d532c"}],"source":"REFERENCES_TAG"},{"range":[{"fixed":"12db9bd2f428b628a62809669c3d76297e07750a"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v2.25.2","v2.25.1","v2.25.0","v2.24.0","v2.23.0","v2.22.1","v2.21.10","v2.21.9","v2.21.8","v2.21.7","v2.21.6","v2.21.5","v2.21.3","v2.21.2","v2.21.1","v2.21.0","v2.20.2","v2.20.1","v2.20.0","v2.19.0","v2.18.0","v2.17.0","v2.16.0","v2.15.1","v2.15.0","v2.14.0","v2.13.0","v2.12.1","v2.12.0","v2.11.3","v2.11.1","v2.11.0","v2.10.1","v2.10.0","v2.9.0","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.0","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.5.4","v2.5.3","v2.4.3","v2.5.2","v2.5.1","v2.5.0","v2.4.2","v2.4.1","v2.4.0","v2.3.1","v2.3.0","v2.2.5","v2.2.4","v2.2.3","v2.2.1","v2.2.0","v2.1.2","v2.1.1","v2.0.8","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v1.65.7","v1.65.6","v1.65.5","v1.65.4","v1.65.3","v1.65.2","v1.65.1","v1.65.0","v1.64.1","v1.64.0","v1.63.0","v1.62.3","v1.62.2","v1.62.1","v1.62.0","v1.61.2","v1.61.0","v1.60.1","v1.60.0","v1.59.0","v1.58.0","v1.57.0","v1.56.0","v1.55.5","v1.54.0","v1.55.4","v1.55.3","v1.55.2","v1.55.1","v1.55.0","v1.54.1","v1.53.0","v1.52.2","v1.52.1","v1.52.0","v1.51.0","v1.50.0","v1.49.1","v1.49.0","v1.48.4","v1.48.3","v1.48.2","v1.48.1","v1.47.0","v1.45.1","v1.44.2","v1.44.1","v1.43.5","v1.43.4","v1.43.3","v1.43.2","v1.43.1","v1.43.0","v1.41.1","v1.41.0","v1.40.1","v1.40.0","v1.39.3","v1.39.2","v1.38.2","v1.38.1","v1.37.4","v1.37.3","v1.37.2","v1.37.1","v1.36.1","v1.35.1","v1.34.1","v1.33.2","v1.33.1","v1.32.1","v1.31.1","v1.30.1","v1.29.1","v1.28.1","v1.27.2","v1.26.1","v1.24.1","v1.23.2","v1.23.1","v1.22.1","v1.10.1","v1.10.0","v1.8.1","v1.7.12","v1.6.12","v1.6.9","v1.6.4","v1.6.2","v1.6.1","1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-115932.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
