Hi, The following vulnerability was published for deepdiff. CVE-2026-33155[0]: | DeepDiff is a project focused on Deep Difference and search of any | Python data. From version 5.0.0 to before version 8.6.2, the pickle | unpickler _RestrictedUnpickler validates which classes can be loaded | but does not limit their constructor arguments. A few of the types | in SAFE_TO_IMPORT have constructors that allocate memory | proportional to their input (builtins.bytes, builtins.list, | builtins.range). A 40-byte pickle payload can force 10+ GB of | memory, which crashes applications that load delta objects or call | pickle_load with untrusted data. This issue has been patched in | version 8.6.2. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
