The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

pypdf is an A pure-python PDF library capable of splitting, merging, cropping, and transforming PDF files
Affected versions of this package are vulnerable to Loop with Unreachable Exit Condition ('Infinite Loop') when the PdfWriter(clone_from)
function is used with a PDF. An attacker can craft a PDF that leads to an infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. This is particularly problematic when the user manipulates an incoming malicious PDF, for example, by merging it with another PDF or by adding annotations.
This vulnerability can be mitigated by modifying pypdf/generic/_data_structures.py
in the same way as in pull request #2264.
