{"id":"CVE-2026-105131","summary":"mayswind ezBookkeeping 1.2.0 before 2.0.1 Privilege Escalation via Token Refresh Endpoint","details":"ezBookkeeping 1.2.0 before 2.0.1 contains a privilege escalation vulnerability that allows attackers holding an API token to obtain a full session token via /api/v1/tokens/refresh.json. Because TokenRefreshHandler never checks token type, attackers can exchange short-lived or IP-restricted API tokens for 30-day normal session tokens that bypass API token expiry and allowlists.","aliases":["GHSA-wq25-mpcf-2mfc"],"modified":"2026-10-05T02:45:45.767905881Z","published":"2026-10-04T01:20:29.985Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105131.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105131.json"},{"type":"ADVISORY","url":"https://github.com/mayswind/ezbookkeeping/releases/tag/v2.0.1"},{"type":"ADVISORY","url":"https://github.com/mayswind/ezbookkeeping/security/advisories/GHSA-wq25-mpcf-2mfc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105131"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mayswind-ezbookkeeping-1.2.0-before-2.0.1-privilege-escalation-via-token-refresh-endpoint"},{"type":"FIX","url":"https://github.com/mayswind/ezbookkeeping/commit/9a92b07be8a7034665abfdb35b036210a1d57bf9"},{"type":"PACKAGE","url":"https://github.com/mayswind/ezbookkeeping"},{"type":"ARTICLE","url":"https://github.com/mayswind/ezbookkeeping/blob/v2.0.0/pkg/api/tokens.go#L327-L380"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mayswind/ezbookkeeping","events":[{"introduced":"4c8bb5a0b7f5a40821fa666dc600caaccde8c1f0"},{"fixed":"323cf0c683d7889ad0c28377039ced1a44167c1e"},{"fixed":"9a92b07be8a7034665abfdb35b036210a1d57bf9"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"1.2.0"},{"fixed":"2.0.1"}]}}],"versions":["v2.0.0","v1.6.0","v1.5.1","v1.5.0","v1.4.0","v1.3.2","v1.3.1","v1.3.0","v1.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-105131.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:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
