Hi, The following vulnerability was published for pypdf. CVE-2025-55197[0]: | pypdf is a free and open-source pure-python PDF library. Prior to | version 6.0.0, an attacker can craft a PDF which leads to the RAM | being exhausted. This requires just reading the file if a series of | FlateDecode filters is used on a malicious cross-reference stream. | Other content streams are affected on explicit access. This issue | has been fixed in 6.0.0. If an update is not possible, a workaround | involves including the fixed code from pypdf.filters.decompress into | the existing filters file. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
