Low (1.2) in pypdf project pypdf. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in pypdf 6.7.2.
pypdf is a free and open-source pure-python PDF library. Prior to 6.7.2, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires reading the file. This has been fixed in pypdf 6.7.2. As a workaround, one may apply the patch manually.
