Attackers can exploit the link auto-formatter's re-processing of already-linked text, using quote characters to break out of the href attribute and inject attacker-controlled markup to execute script in the victim's session.\n\n## Affected\n\n- `gfi_kerioconnect < 10.0.9p2`\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,"exploitation":0,"ransomware":0},"changes":[]}
