CVE-2026-26273 is a critical broken authentication vulnerability affecting Known social publishing platform versions 1.6.2 and earlier. An unauthenticated attacker can exploit this by querying a user's email on the password reset page, which inadvertently leaks the password reset token in a hidden HTML field. This allows for full account takeover without needing access to the victim's email. The vulnerability has a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
