CitrixBleed 2: The Unpatchable Comedy of Errors in Cybersecurity
Over 3,300 Citrix NetScaler devices are still unpatched against the critical CitrixBleed 2 vulnerability, CVE-2025-5777, leaving them open to authentication bypass via hijacked user sessions. Despite patches being available for months, these devices are still prime targets for attackers with a taste for outdated tech and unpatched exploits.
Hot Take:
Citrix must feel like it’s caught in a time loop of déjà vu! Just when they thought they’d patched up all the holes, a new wave of cyber shenanigans crashes through. It’s like playing whack-a-mole, but with vulnerabilities. Someone hand them a bigger mallet or at least a ticket to a cybersecurity spa day. After all, patching up a 3,300-device-sized headache isn’t exactly what you call a relaxing stroll through the digital park.
