CVE-2026-59990
The open-source JSON parser Jawn is vulnerable to a denial of service attack due to uncontrolled nesting depth in JSON arrays and objects. An attacker can submit untrusted JSON to grow parser contexts until the JVM heap is exhausted , triggering a java.lang.OutOfMemoryError that is not handled by...
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...

CVE-2026-61814 Jawn: Quadratic parsing effort in AsyncParser
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...

CVE-2026-61814
The Jawn open-source JSON parser is vulnerable to a denial of service (DoS) attack via CPU exhaustion in its AsyncParser component. The root cause is that AsyncParser can perform quadratic work (O(n^2)) when a single JSON token is delivered across many small chunks, as each absorb call rescans th...
