TCPDF Project maintains a narrowly scoped PHP library for PDF generation that, despite its modest CVE volume, occupies a notable position across web applications and content-management systems that embed it. Vulnerabilities affecting the library skew toward serious outcomes and recur through input-validation and neutralization weaknesses such as cross-site scripting, type confusion, and improper certificate validation, alongside configuration and exposure issues that arise when PDF generation handles untrusted input or is deployed with insufficient access controls. Defenders should treat PDF-generation integrations as a patching priority when this vendor releases updates; live severity and exploitation figures are shown alongside this summary.
