CVE-2026-69249

python-cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, when resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an...

GHSA-JWV3-5HGF-82WW python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

Summary When resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential blowup. Although the limitation that the chain depth cannot exceed a specified maximum depth prevents...

CVE-2026-69249

CVE-2026-69249 affects python-cryptography prior to 49.0.0, where resolving invalid certificate chains with duplicate self-signed intermediates can explode in recursion, causing resource exhaustion DoS. The core issue is in the recursive build_chain_inner not de-duplicating previously analyzed ca...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

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...
