UBUNTU-CVE-2026-102998

pypdf is a free and open-source pure-python PDF library. Prior to 6.19.0, a crafted PDF with form field values can cause pypdf/generic/appearancestream.py appearance-stream generation to repeat invariant selection-data work inside a loop when an application updates fields with flattening enabled,...

CVE-2026-102090

Kiteworks Core before version 9.5.1 is vulnerable to Content Injection. A URL parameter in the PDF viewer was insufficiently validated, allowing an attacker-controlled document to be loaded and displayed under the trust of the legitimate application domain. This could increase the credibility of...

CVE-2026-102998

A flaw was found in pypdf. A remote attacker can exploit this issue by submitting a specially crafted PDF document with specific form field values. When an application updates these fields with flattening enabled, redundant computational operations are repeated inside a loop during appearance...

CVE-2026-102996

A flaw was found in pypdf. This vulnerability allows an attacker to cause a Denial of Service DoS by providing a specially crafted PDF document with an oversized font character width array. When processing the document during operations such as text extraction, the library allocates excessive...

CVE-2026-102994

A flaw was found in pypdf. By supplying a specially crafted PDF document containing excessively long indirect object identifiers or generation tokens without whitespace, a remote attacker can trigger unbounded input scanning during parsing. This issue causes significant processing delays and...
