Both directly encoded and double-encoded external URLs can trigger the issue, depending on which validation path is used. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":33.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":222597,"id":"CVE-2026-79650","ts":1792084778249,"field":"cvss","old":null,"new":"6.1"},{"seq":222596,"id":"CVE-2026-79650","ts":1792084778249,"field":"severity","old":"none","new":"medium"}]}
