Arbitrary file read via template path traversal
Published Mar 15, 2023 · Updated Feb 27, 2025
Path traversal in swig through 1.4.2 and swig-templates through 2.0.4 allows remote attackers to read arbitrary local files. The renderFile path resolver accepts traversal segments in include or extends tag values and resolves them outside the template directory. Exploitation requires an application to render an attacker-controlled template; the demonstrated consequence is file disclosure only.
