CVE-2026-49844

A flaw was found in Apache Log4j API. This vulnerability occurs due to improper encoding of non-finite floating-point values during JSON serialization of MapMessages, leading to invalid JSON output. An attacker who can supply a non-finite value can exploit this to cause the affected logging layou...

CVE-2026-67215

cJSON through 1.7.19 is vulnerable to uncontrolled recursion leading to stack exhaustion when an untrusted RFC 6902 JSON Patch is applied via cJSONUtilsApplyPatches or cJSONUtilsApplyPatchesCaseSensitive. A patch containing add and copy operations grafts duplicated subtrees to amplify document...

CVE-2026-67217

cJSON through 1.7.19 applies RFC 6902 JSON Patch operations non-atomically in applypatch in cJSONUtils.c. For a replace operation that is missing its value member, or a move operation whose destination path cannot be resolved, the existing target member is detached and deleted before the operatio...

CVE-2026-67216

cJSON through 1.7.19 contains an inefficient algorithmic complexity flaw in cJSONCompare. When comparing objects, the function recurses into each shared subtree twice, once in each direction, with no depth guard, making the running time exponential in nesting depth. A small, deeply nested documen...

json: Ruby JSON: Denial of service via heap buffer overflow with oversized streamed objects

A flaw was found in Ruby JSON. A remote attacker could exploit a heap buffer overflow vulnerability by providing an oversized streamed object containing a specially crafted string. This could lead to a reliable process crash, resulting in a denial of service DoS for the affected system...
