{"id":"CVE-2026-62376","state":"PUBLISHED","title":"Vikunja: Plaintext storage of password-reset/email-confirm tokens in database enables account takeover on DB read access","description":"Vikunja is an open-source self-hosted task management platform. Versions prior to 2.4.0 store password-reset, email-confirmation, and account-deletion tokens in the `user_tokens` table in plaintext. If an attacker gains read access to the database through a backup leak, misconfigured storage, or SQL-level exposure, they can immediately use pending tokens to take over user accounts without knowing passwords. Version 2.4.0 fixes the issue.","publishedAt":"2026-10-09T20:50:35.524Z","updatedAt":"2026-10-13T18:31:03.228Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["go-vikunja vikunja"],"affected":[{"vendor":"go-vikunja","product":"vikunja","versions":[{"version":"< 2.4.0","status":"affected"}]}],"references":["https://github.com/go-vikunja/vikunja/security/advisories/GHSA-r6w9-259g-gwrv","https://github.com/go-vikunja/vikunja/commit/00fd2c6155c01faae99be4226b931d8091fd6323","https://github.com/go-vikunja/vikunja/commit/3a0ea15d8c18ff960bc98ae39950fa7a14b0af7d","https://github.com/go-vikunja/vikunja/commit/e31ea2de5040fa63bc97cf4df63bafed3bd9ad85","https://github.com/go-vikunja/vikunja/releases/tag/v2.4.0"],"weaknesses":["CWE-312","CWE-916"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/62xxx/CVE-2026-62376.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-62376","state":"PUBLISHED","datePublished":"2026-10-09T20:50:35.524Z","dateUpdated":"2026-10-13T18:31:03.228Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-13T22:04:59.678Z"},"containers":{"cna":{"title":"Vikunja: Plaintext storage of password-reset/email-confirm tokens in database enables account takeover on DB read access","descriptions":[{"lang":"en","value":"Vikunja is an open-source self-hosted task management platform.
