    CISA adds TP-Link and WhatsApp flaws to KEV catalog amid active exploitation

    Industry Or Public Sector Update

    CISA adds the TP-Link TL-WA855RE vulnerability CVE-2020-24363 and the WhatsApp vulnerability CVE-2025-55177 to its Known Exploited Vulnerabilities catalog after evidence of active exploitation. The TP-Link flaw is a missing authentication weakness that can let an unauthenticated attacker on the same network send a TDDP_RESET POST request for a factory reset and reboot, then set a new administrative password, while the WhatsApp issue was exploited in a highly targeted spyware campaign by chaining it with CVE-2025-43300 and prompted in-app threat notifications to less than 200 users.
