CVE-2026-76070: Stack-based Buffer Overflow

Netis NC63 firmware through V3.0.0.3327 contains a stack-based buffer overflow vulnerability that allows unauthenticated remote attackers to overwrite saved stack state by submitting an oversized Base64-encoded password to the login handler in /bin/netis.cgi. Attackers can exploit the custom Base...

PYSEC-2026-3724

NLTK versions before 3.9.4 contain an unbounded recursion vulnerability in JSONTaggedDecoder.decodeobj that allows attackers to cause denial of service by supplying deeply nested JSON structures. Attackers can craft JSON payloads exceeding the recursion limit to trigger an unhandled RecursionErro...

CVE-2026-77118

A flaw was found in GraphicsMagick. A heap out-of-bounds write vulnerability exists in the Photo CD PCD decoder. A remote attacker could exploit this by providing a specially crafted PCD file. Processing this file can lead to corruption of heap memory, potentially resulting in arbitrary code...
