CVE-2026-59977
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
In ConvertX before 0.18.0, the /delete/{id} endpoint uses HTTP GET for permanent deletion without CSRF protection. If an authenticated user visits attacker-controlled content, the browser sends the session cookie and deletes the targeted job.
Risk Assessment
An attacker can cause unauthorized loss of converted-file history for victims. This affects data integrity and may hinder auditing or recovery of conversion results.
Recommendation
Update ConvertX to version 0.18.0 or later. Until patched, consider restricting access to the /delete/{id} endpoint or enforcing non-GET methods.
Other vulnerabilities in ConvertX
See all- CVE-2026-105080Critical
In ConvertX before 0.19.0, converters/calibre.ts does not block recipe files and passes them to the ebook-convert program from Calibre. This allows executable code in .recipe or .downloaded_recipe files.
- CVE-2026-59976High
In ConvertX before 0.18.0, the ImageMagick converter uses the unsanitized convert_to parameter to construct an output path. An authenticated user (or unauthenticated when access is allowed) can upload an extensionless image and supply directory traversal sequences in convert_to via /convert, writing output outside the intended directory.
- CVE-2026-108694Medium
ConvertX through 0.19.0 contains an arbitrary file read vulnerability that allows authenticated users to read server files because src/converters/pandoc.ts invokes Pandoc without the --sandbox flag. Attackers can upload a reStructuredText document with an include directive naming an absolute path, convert it, and download output containing the referenced file's contents.
- CVE-2026-85618Medium
ConvertX 0.17.0 contains an arbitrary file read vulnerability in the xelatex converter that allows authenticated users to read files by uploading LaTeX files with input directives. Attackers can upload .tex files containing \\input{path} or \\verbatiminput{path} directives to have the TeX engine read arbitrary files accessible to the server process and include them in downloadable PDF output.
- CVE-2025-66449High
ConvertX, a self-hosted online file converter, in versions prior to 0.16.0, the `/upload` endpoint allows an authenticated user to write arbitrary files on the system, overwriting binaries and allowing code execution. The upload function takes `file.name` directly from user supplied data without sanitization, allowing arbitrary file write.
Original NVD description (English source)
ConvertX is a self-hosted file conversion service. Prior to 0.18.0, the /delete/{id} endpoint uses HTTP GET for permanent deletion without CSRF protection. If an authenticated user visits attacker-controlled content that requests /delete/{id}, the browser sends the user session cookie and the request deletes the targeted job, resulting in unauthorized loss of converted-file history. This issue is fixed in version 0.18.0.
