Serena: Unauthenticated Flask dashboard on fixed port enables DNS rebinding → memory poisoning → RCE

Summary Serena's built-in web dashboard exposes an unauthenticated Flask API on a fixed, predictable port TCP 24282, hardcoded as 0x5EDA in constants.py. The server has no authentication, no CSRF protection, and no Host header validation. A DNS rebinding attack allows a malicious webpage to reach...

Permissive Cross-domain Policy with Untrusted Domains

Overview Affected versions of this package are vulnerable to Permissive Cross-domain Policy with Untrusted Domains through the unauthenticated local API exposed in proxy mode, which accepts cross-origin requests due to a permissive CORS policy and lack of authentication. An attacker can achieve...

GHSA-MXWC-WH95-PW4G Trapster Community: Unauthenticated malformed DNS compression pointers crash per-packet honeypot handler

Summary trapster.libs.dns.decodelabels decodes DNS names from attacker-supplied UDP packets and recurses once per RFC 1035 compression pointer with no cycle detection and no depth bound. A single unauthenticated UDP datagram sent to the DNS honeypot drives the function past CPython's recursion...

Uncontrolled Recursion

Overview trapster is a Trapster Daemon Affected versions of this package are vulnerable to Uncontrolled Recursion through the decodelabels function. An attacker can cause the application to crash and disrupt service by sending specially crafted UDP packets containing malformed DNS compression...

CVE-2026-59802

PasswordPusher before 2.8.1 accepts data URI schemes in URL push payloads due to insufficient validation in the validurl function. Attackers can create malicious pushes containing data:text/html URIs that execute arbitrary JavaScript in victims' browsers when clicked, enabling phishing and...
