{"id":"CVE-2026-29782","summary":"OpenSTAManager: Remote Code Execution via Insecure Deserialization in OAuth2","details":"OpenSTAManager is an open source management software for technical assistance and invoicing. Prior to version 2.10.2, the oauth2.php file in OpenSTAManager is an unauthenticated endpoint ($skip_permissions = true). It loads a record from the zz_oauth2 table using the attacker-controlled GET parameter state, and during the OAuth2 configuration flow calls unserialize() on the access_token field without any class restriction. This issue has been patched in version 2.10.2.","aliases":["GHSA-whv5-4q2f-q68g"],"modified":"2026-07-08T08:12:26.164764605Z","published":"2026-04-02T13:42:25.134Z","database_specific":{"cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29782.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/devcode-it/openstamanager/releases/tag/v2.10.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29782.json"},{"type":"ADVISORY","url":"https://github.com/devcode-it/openstamanager/security/advisories/GHSA-whv5-4q2f-q68g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29782"},{"type":"FIX","url":"https://github.com/devcode-it/openstamanager/commit/d2e38cbdf91a831cefc0da1548e02b297ae644cc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/devcode-it/openstamanager","events":[{"introduced":"0"},{"fixed":"7c245094972386850964d5216ad28e8160ae1e53"},{"fixed":"d2e38cbdf91a831cefc0da1548e02b297ae644cc"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.10.2"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:devcode:openstamanager:*:*:*:*:*:*:*:*"}}],"versions":["v2.10.1","v2.10-beta","v2.9.1","v2.6.2","v2.6.1","v2.5.5","v2.5.4","v2.5.3","v2.5.2-beta","v2.5.1-beta","v2.5","v2.4.54","v2.4.53","v2.4.51","v2.4.49","v2.4.47","v2.4.44","v2.4.43","v2.4.42","v2.4.41","v2.4.40","v2.4.38","v2.4.32","v2.4.28","v2.4.25","v2.4.24","v2.4.23","v2.4.22","v2.4.20","v2.4.17","v2.4.16","v2.4.14","v2.4.13","v2.4.12","v2.4.11","v2.4.10","v2.4.9","v2.4.8","v2.4.6","v2.4.4","v2.4.3","v2.4.2","v2.4","v2.3-beta.2","v2.3-beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29782.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
