CVE-2026-119342: Stirling-PDF: SVG→PDF local file read (LFI) via SVG-sanitizer and Batik same-origin bypass
Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.
Generated by VEDAS. Scores as of 2026-11-08 00:03 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.
What it is
Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. From 2.13.1 until 2.13.2, the POST /api/v1/convert/svg/pdf endpoint renders attacker-supplied SVG through Apache Batik, and a scheme-less root-relative image reference bypasses SvgSanitizer.isExternalUrl() before Batik resolves it against the file:///input.svg document base as a same-origin local file. The convert() and addSvgAsPage() paths in app/core/src/main/java/stirling/software/SPDF/utils/SvgToPdf.java can then render image-decodable server files into the returned PDF when sanitization is enabled, including without authentication on login-disabled deployments or with non-admin access when login is enabled. The issue discloses PNG, JPG, GIF, or SVG content and provides an existence oracle only for image-decodable paths; plain text, binary files, directories, XInclude text, external entities, explicit file URLs, and tested HTTP references are not disclosed through this mechanism. This issue is fixed in version 2.13.2.
Description quoted from the CVE record (assigned by GitHub_M, published 2026-10-30).
Weakness: CWE-20: Improper Input Validation; CWE-22: Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’); CWE-610: Externally Controlled Reference to a Resource in Another Sphere; CWE-918: Server-Side Request Forgery (SSRF)
How it can be exploited
Exploitable over the network with low attack complexity needing no privileges and no user interaction. Impact: confidentiality low, integrity none, availability none. CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
CISA assessment (SSVC): CISA assesses that a public proof of concept exists. Automatable: yes. Technical impact: partial.
