CVE-2026-27628 2 Py-pdf, Pypdf Project 2 Pypdf, Pypdf 2026-04-16 7.5 High
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.
CVE-2026-28351 2 Py-pdf, Pypdf Project 2 Pypdf, Pypdf 2026-04-16 5.3 Medium
pypdf is a free and open-source pure-python PDF library. Prior to version 6.7.4, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream using the RunLengthDecode filter. This has been fixed in pypdf 6.7.4. As a workaround, consider applying the changes from PR #3664.
CVE-2026-28804 2 Py-pdf, Pypdf Project 2 Pypdf, Pypdf 2026-04-16 5.3 Medium
pypdf is a free and open-source pure-python PDF library. Prior to version 6.7.5, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires accessing a stream which uses the /ASCIIHexDecode filter. This issue has been patched in version 6.7.5.
CVE-2026-31826 2 Py-pdf, Pypdf Project 2 Pypdf, Pypdf 2026-04-16 5.5 Medium
pypdf is a free and open-source pure-python PDF library. Prior to 6.8.0, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing a content stream with a rather large /Length value, regardless of the actual data length inside the stream. This vulnerability is fixed in 6.8.0.
CVE-2026-33699 2 Py-pdf, Pypdf Project 2 Pypdf, Pypdf 2026-04-02 7.5 High
pypdf is a free and open-source pure-python PDF library. Versions prior to 6.9.2 have a vulnerability in which an attacker can craft a PDF which leads to an infinite loop. This requires reading a file in non-strict mode. This has been fixed in pypdf 6.9.2. If users cannot upgrade yet, consider applying the changes from the patch manually.
CVE-2026-33123 2 Py-pdf, Pypdf Project 2 Pypdf, Pypdf 2026-03-25 6.5 Medium
pypdf is a free and open-source pure-python PDF library. Versions prior to 6.9.1 allow an attacker to craft a malicious PDF which leads to long runtimes and/or large memory usage. Exploitation requires accessing an array-based stream with many entries. This issue has been fixed in version 6.9.1.
