CVE-2026-62995

CVE-2026-62995 affects the Python library joserfc (versions ≤ 1.7.1). The issue: joserfc accepts JWTs with trailing padding (==), which is non-conforming to JOSE specs and enables JWT malleability when parsed by the library. Practical impact varies by deployment and could allow bypass of token re...

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-2026-67217

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-2026-67215

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...

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...
