Name of the Vulnerable Software and Affected Versions cbor2 versions prior to 5.9.0 Description The cbor2 library is susceptible to a Denial of Service DoS attack due to uncontrolled recursion when decoding deeply nested CBOR structures. This affects both the pure Python implementation and the C...

CVE-2025-68131 CBORDecoder reuse can leak shareable values across decode calls

cbor2 provides encoding and decoding for the Concise Binary Object Representation CBOR serialization format. Starting in version 3.0.0 and prior to version 5.8.0, whhen a CBORDecoder instance is reused across multiple decode operations, values marked with the shareable tag 28 persist in memory an...

CVE-2025-64076

CVE-2025-64076 affects the cbor2 library (Python CBOR) via the C extension decode_definite_long_string() in source/decoder.c. The advisory describes two issues: (1) an integer underflow in chunk processing leads to out-of-bounds reads, potentially triggering resource exhaustion; (2) a missing Py_...
