Attackers with read access to those logs can replay an unredeemed password-reset token to take over the account or an account-deletion token to confirm the deletion.","epss":{"date":"2026-11-10","percentile":0.18676,"score":0.00266},"exploits":[],"kev":null,"metrics":[{"score":8.4,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.1,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},{"score":8.4,"severity":"high","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":6.1,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N","version":"3.1"}],"modifiedAt":1794486098415,"publishedAt":1794101845205,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-qf5p-grf5-wcq4"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/vikunja-before-2.7.1-sensitive-token-exposure-via-url-query-in-access-logs"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-qf5p-grf5-wcq4"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/vikunja-before-2.7.1-sensitive-token-exposure-via-url-query-in-access-logs"}],"remediation":[],"revision":"aee5fba58d55a2ec33ed57a82fbf8ba6e5bab56a813c7ae3c705a28bb8153795","sources":[{"modifiedAt":1794486098415,"name":"CNA: VulnCheck","retrievedAt":1794488919684,"url":"https://www.cve.org/CVERecord?id=CVE-2026-123512"},{"modifiedAt":1794104199967,"name":"NVD","retrievedAt":1794118559932,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-123512"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794377576773,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-123512"}],"ssvc":{"assessedAt":1794486085785,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Vikunja before 2.7.1 Sensitive Token Exposure via URL Query in Access Logs","updatedAt":1794488919684}
