Name of the Vulnerable Software and Affected Versions go-ipld-prime versions prior to 0.22.0 Description go-ipld-prime’s DAG-CBOR decoder does not limit the size of preallocations for maps and lists based on CBOR headers, potentially leading to excessive memory allocation from small payloads...

GHSA-5JG4-P4QW-CGFR @stablelib/cbor: Stack exhaustion Denial of Service via deeply nested CBOR arrays, maps, or tags

Summary @stablelib/cbor decodes nested CBOR structures recursively and does not enforce a maximum nesting depth. A sufficiently deep attacker-controlled CBOR payload can therefore crash decoding with RangeError: Maximum call stack size exceeded. Details The decoder processes arrays, maps, and...

OESA-2026-1780 python-pyasn1 security update
