PLEASE NOTE: iText 5 is EOL, and has been replaced by iText 7. Only security fixes will be added

Known Security Issues

org.apache.santuario:xmlsec vulnerabilities

The iText 5 targets Java 5 which means that we can not update org.apache.santuario:xmlsec version to 2.x.x or newer as it requires Java 8. If you are not using the com.itextpdf.text.pdf.security.MakeXmlSignature class then you can avoid adding org.apache.santuario:xmlsec dependency into your project. Which means that you would not be affected by the related vulnerabilities, for example https://snyk.io/vuln/SNYK-JAVA-ORGAPACHESANTUARIO-1655558. If you are using com.itextpdf.text.pdf.security.MakeXmlSignature class, for example for XFA signatures, then you can:

• either use org.apache.santuario:xmlsec 1.5.8 as a dependency which is affected by the vulnerability specified above, but works on Java 5+;
• or use org.apache.santuario:xmlsec 2.1.7 or newer. But this would require java 8+ and affects on the output format (see https://issues.apache.org/jira/browse/SANTUARIO-494).

We HIGHLY recommend customers use iText 7 for new projects, and to consider moving existing projects from iText 5 to iText 7 to benefit from the many improvements such as:

• HTML to PDF (PDF/UA) conversion
• PDF Redaction
• SVG support
• Better language support: Indic, Thai, Khmer, Arabic, Hebrew. (Close-source addon)
• PDF Debugging for your IDE
• Data Extraction
• Better continued support and bugfixes
• More modular, extensible handling of your document workflow
• Extra practical add-ons
• Encryption, hashing & digital signatures
