Prior to 3.0.0, the password change endpoint (POST /current/user/password) accepts a valid client token without requiring the account's current password or another elevated authentication step. An attacker who obtains a client token can set a new password for the associated user, taking control of password authentication and forcing account recovery through an administrator or direct database access. This issue is fixed in version 3.0.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-620"],"references":["https://github.com/gotify/server/commit/a8744482c668e07a61798573ec8e17bd3f6009f9","https://github.com/gotify/server/pull/952","https://github.com/gotify/server/releases/tag/v3.0.0","https://github.com/gotify/server/security/advisories/GHSA-3hcj-9m7p-wwm9","https://github.com/gotify/server/security/advisories/GHSA-3hcj-9m7p-wwm9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-102603","score":0.00335,"percentile":0.26667,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3hcj-9m7p-wwm9","url":"https://osv.dev/vulnerability/GHSA-3hcj-9m7p-wwm9","summary":"Gotify: Insufficiently Protected Password Change endpoint","modified":"2026-10-19T21:41:12.735924686Z","packages":[{"ecosystem":"Go","name":"github.com/gotify/server/v2","purl":"pkg:golang/github.com/gotify/server/v2","ranges":["<=2.9.1"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gotify/server/v3","purl":"pkg:golang/github.com/gotify/server/v3","ranges":["<3.0.0"],"fixed":["3.0.0"]}]},{"id":"GO-2026-6772","url":"https://osv.dev/vulnerability/GO-2026-6772","summary":"Gotify: Insufficiently Protected Password Change endpoint in github.com/gotify/server","modified":"2026-10-19T21:31:37.901957888Z","packages":[{"ecosystem":"Go","name":"github.com/gotify/server","purl":"pkg:golang/github.com/gotify/server","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gotify/server/v2","purl":"pkg:golang/github.com/gotify/server/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gotify/server/v3","purl":"pkg:golang/github.com/gotify/server/v3","ranges":["<3.0.0"],"fixed":["3.0.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
