Prior to 1.0.2, `resetPasswordForToken` updates the password row without invalidating database-backed sessions.

This issue is fixed in version 1.0.2.\n\n## Affected\n\n- `coop < 1.0.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":13,"depthScoreParts":{"impact":12.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
