Prior to 2.3.0, the addRepeatIntervalToTime function uses an O(n) loop that advances a date by the task's RepeatAfter duration until it exceeds the current time. By creating a repeating task with a 1-second interval and a due date far in the past, an attacker triggers billions of loop iterations, consuming CPU and holding a database connection for minutes per request. This vulnerability is fixed in 2.3.0.","state":0,"publishedAt":"2026-04-10T17:17:03.52+00:00","modifiedAt":"2026-10-26T21:10:00.17+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/go-vikunja/vikunja/commit/6df0d6c8f54b01db6464c42810e40e55f12b481b","https://github.com/go-vikunja/vikunja/pull/2577","https://github.com/go-vikunja/vikunja/releases/tag/v2.3.0","https://github.com/go-vikunja/vikunja/security/advisories/GHSA-r4fg-73rc-hhh7"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35599","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-407"],"productCriteria":["cpe:2.3:a:vikunja:vikunja:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-04-10T17:17:03.520","lastModified":"2026-10-26T21:10:00.170"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
