{"id":"CVE-2025-54433","summary":"Bugsink is vulnerable to Path Traversal attacks via event_id in ingestion","details":"Bugsink is a self-hosted error tracking service. In versions 1.4.2 and below, 1.5.0 through 1.5.4, 1.6.0 through 1.6.3, and 1.7.0 through 1.7.3,  ingestion paths construct file locations directly from untrusted event_id input without validation. A specially crafted event_id can result in paths outside the intended directory, potentially allowing file overwrite or creation in arbitrary locations. Submitting such input requires access to a valid DSN, potentially exposing them. If Bugsink runs in a container, the effect is confined to the container’s filesystem. In non-containerized setups, the overwrite may affect other parts of the system accessible to that user. This is fixed in versions 1.4.3, 1.5.5, 1.6.4 and 1.7.4.","aliases":["GHSA-q78p-g86f-jg6q","PYSEC-2026-1226"],"modified":"2026-08-12T03:51:48.338626056Z","published":"2025-07-30T14:29:03.510Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/54xxx/CVE-2025-54433.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/54xxx/CVE-2025-54433.json"},{"type":"ADVISORY","url":"https://github.com/bugsink/bugsink/security/advisories/GHSA-q78p-g86f-jg6q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-54433"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/1001726f4389e982c486cdd5fa81941cb46cfc33"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/211ddf76758c808c095b5f836c363f148d934d21"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/2c41fbe3881bdea83399a7f9fdc8cff198ae089f"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/53cf1a17a3e96f7c83c7451fd56f980a09d0c9b0"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/55a155003d0b416ea008c5e7dcde85130ad21d9b"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/b94aa8a5c96ce8cdd9711b6beb4e518264993ac2"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/c341687bd655543730c812db35c29199f788be6b"},{"type":"FIX","url":"https://github.com/bugsink/bugsink/commit/c87217bd565122ba70af90436e3ab2cd9bee658f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bugsink/bugsink","events":[{"introduced":"dd339f73de93fe6d5f92fd45f81504e2dcfd63a4"},{"fixed":"4de7bfe1df8110a7bbd940d4ed177137e66ea645"},{"introduced":"b53b1c6ce2bd6f44d75d238f11fe1309ae342a3e"},{"fixed":"0e3bbd9ab5b8bd67456027553228ca0403e2783e"},{"introduced":"6ec220b3d2619866975c6f65bc3b266673928fc7"},{"fixed":"fd80eff7ca780cce7626de52b330b0344e098f1b"},{"fixed":"1001726f4389e982c486cdd5fa81941cb46cfc33"},{"fixed":"211ddf76758c808c095b5f836c363f148d934d21"},{"fixed":"2c41fbe3881bdea83399a7f9fdc8cff198ae089f"},{"fixed":"53cf1a17a3e96f7c83c7451fd56f980a09d0c9b0"},{"fixed":"55a155003d0b416ea008c5e7dcde85130ad21d9b"},{"fixed":"b94aa8a5c96ce8cdd9711b6beb4e518264993ac2"},{"fixed":"c341687bd655543730c812db35c29199f788be6b"},{"fixed":"c87217bd565122ba70af90436e3ab2cd9bee658f"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"1.5.0"},{"fixed":"1.5.4"},{"introduced":"1.6.0"},{"fixed":"1.6.3"},{"introduced":"1.7.0"},{"fixed":"1.7.3"}]}}],"versions":["1.5.4","1.6.3","1.7.3","1.7.2","1.7.1","1.7.0","1.6.2","1.6.1","1.6.0","1.5.3","1.5.2","1.5.1","1.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-54433.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
