Uncontrolled Recursion

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Uncontrolled Recursion via the load method in jwt/apijws.py when parsing a JWT with a deeply nested recursive JSON structure in the header. An attacker can supply a JWT whose header contains...

Linux Distros Unpatched Vulnerability : CVE-2026-59990

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Jawn is an open source JSON parser. Prior to 1.7.0, Jawn parse methods accept arbitrarily deep JSON array and object nesting without a depth limit, allowing a...

Linux Distros Unpatched Vulnerability : CVE-2026-61814

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Jawn is an open source JSON parser. Prior to 1.7.0, Jawn's AsyncParser can perform quadratic work when a single JSON token is delivered across many small chunks...

com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...

Jawn: Uncontrolled nesting depth in JSON parser

The Jawn parser before 1.6.1 is vulnerable to a denial of service attack via untrusted input. Impact A remote attacker who can submit JSON to any jawn-backed parse method can exhaust JVM heap and trigger java.lang.OutOfMemoryError. This is treated by Scala as a fatal error and not typically handl...

DEBIAN-CVE-2026-59990

Jawn is an open source JSON parser. Prior to 1.7.0, Jawn parse methods accept arbitrarily deep JSON array and object nesting without a depth limit, allowing a remote attacker who can submit untrusted JSON to grow parser contexts until the JVM heap is exhausted. The resulting...

DEBIAN-CVE-2026-61814

Jawn is an open source JSON parser. Prior to 1.7.0, Jawn's AsyncParser can perform quadratic work when a single JSON token is delivered across many small chunks because each absorb call rescans the incomplete token from the start. A remote attacker who controls untrusted JSON input and its chunk...
