An attacker with write permissions to the database table managed by JdbcAssertingPartyMetadataRepository (saml2_asserting_party_metadata) may be able to store malicious serialized payloads in the columns containing the collection of verification or encryption credentials (verification_credentials and encryption_credentials, respectively). Affected versions: Spring Security 7.0.0 through 7.0.5.

——29Deserialization of untrusted data in Microsoft Office SharePoint allows an unauthorized attacker to execute code over a network.3dCVE-2025-560059.8 CRI96.7%
——29An undocumented and unsafe feature in the PLY (Python Lex-Yacc) library 3.11 allows Remote Code Execution (RCE) via the `picklefile` parameter in the `yacc()` function. This parameter accepts a `.pkl` file that is deserialized with `pickle.load()` without validation. Because `pickle` allows execution of embedded code via `__reduce__()`, an attacker can achieve code execution by passing a malicious pickle file. The parameter is not mentioned in official documentation or the GitHub repository, yet it is active in the PyPI version. This introduces a stealthy backdoor and persistence risk. NOTE: A third-party states that this vulnerability should be rejected because the proof of concept does not demonstrate arbitrary code execution and fails to complete successfully.3d
