Stirling-PDF 3.0.0 through 3.2.0 contains an authorization bypass vulnerability that allows authenticated users to access other users' stored files by pointing a processing folder at the server storage directory. Attackers can create a folder via POST /api/v1/processing-folders targeting storage/<victimUserId>, list files, and run pipelines to read, modify, or destroy victims' files.

Stirling-PDF from 2.13.2 through 3.2.0 contains an incomplete denylist in DatabaseService.validateSqlContent() that allows administrators to bypass H2 import restrictions using CREATE OR REPLACE ALIAS. Authenticated administrators can upload a crafted SQL backup to the import-database endpoint, where RUNSCRIPT defines H2 Java function aliases and restores Java-method execution.

Oct 14, 2026Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files.CVE-2026-85714 · Other software · Stirling-Tools · reported by GitHubCritical 9.1
Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 2.13.2, an authenticated administrator using the default H2 database and security mode can upload a crafted SQL file to POST /api/v1/database/import-database. DatabaseService.validateSqlContent() splits normalized input on semicolons and accepts a statement when it contains any allowed keyword, allowing dangerous H2 functions such as FILE_READ and CSVWRITE, plus CREATE ALIAS, to bypass the insufficient whitelist and execute side effects when RUNSCRIPT processes the file. This permits arbitrary file access. The demonstrated operating-system command execution chain writes attacker-controlled startup files to a user-site location and then triggers an application Python interpreter configured to load those startup files, resulting in command execution as the JVM service account. This issue is fixed in version 2.13.2.

Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 2.9.0, the /api/v1/pipeline/handleData endpoint in app/core/src/main/java/stirling/software/SPDF/controller/api/pipeline/PipelineProcessor.java injects the STIRLING-PDF-BACKEND-API-USER API key into pipeline subrequests, allowing an authenticated ROLE_USER to retrieve the key through /api/v1/user/get-api-key, impersonate the internal service account, bypass normal rate limits, and access internal endpoints including /api/v1/info/requests/all and /api/v1/info/load/all. This issue is fixed in version 2.9.0.

Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 2.0.0, the Get Info workflow in app/core/src/main/resources/templates/security/get-info-on-pdf.html inserts untrusted PDF Title and Author metadata into the summary-text element with innerHTML, allowing a malicious PDF to execute stored cross-site scripting when a user clicks Get Info and to access browser-session data or modify page content. This issue is fixed in version 2.0.0.

Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. In versions prior to 2.0.0, file upload endpoints render user-supplied filenames directly into HTML using unsafe methods like innerHTML without sanitization. An attacker can craft a file with a malicious filename containing JavaScript that executes in the uploading user's browser context, resulting in reflected XSS. The issue affects numerous upload endpoints across the application. The issue has been fixed in version 2.0.0.

Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files. In version 2.7.3, the /api/v1/convert/eml/pdf endpoint with parameter downloadHtml=true returns unsanitized HTML from the email body with Content-Type: text/html. An attacker who sends a malicious email to a Stirling-PDF user can achieve JavaScript execution when that user exports the email using the "Download HTML intermediate file" feature. Version 2.8.0 fixes the issue.

Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files. Versions starting in 2.1.5 and prior to 2.5.2 have Denial of Service (DoS) vulnerability in the Stirling-PDF watermark functionality (`/api/v1/security/add-watermark` endpoint). The vulnerability allows authenticated users to cause resource exhaustion and server crashes by providing extreme values for the `fontSize` and `widthSpacer` parameters. Version 2.5.2 patches the issue.

Stirling-PDF is a locally hosted web application that performs various operations on PDF files. In versions prior to 2.5.2, the /api/v1/convert/markdown/pdf endpoint extracts user-supplied ZIP entries without path checks. Any authenticated user can write files outside the intended temporary working directory, leading to arbitrary file write with the privileges of the Stirling-PDF process user (stirlingpdfuser). This can overwrite writable files and compromise data integrity, with further impact depending on writable paths. The issue was fixed in version 2.5.2.

Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files. Prior to version 0.45.0, Stirling-PDF is vulnerable to SSRF-induced arbitrary file read. WeasyPrint redefines a set of HTML tags, including img, embed, object, and others. The references to several files inside, allow the attachment of content from any webpage or local file to a PDF. This allows the attacker to read any file on the server, including sensitive files and configuration files. All users utilizing this feature will be affected. This issue has been patched in version 0.45.0.

Nov 11, 2024Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files.CVE-2024-52286 · Other software · Stirling-Tools · reported by GitHubLow 2
Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files. In affected versions the Merge functionality takes untrusted user input (file name) and uses it directly in the creation of HTML pages allowing any unauthenticated to execute JavaScript code in the context of the user. The issue stems to the code starting at `Line 24` in `src/main/resources/static/js/merge.js`. The file name is directly being input into InnerHTML with no sanitization on the file name, allowing a malicious user to be able to upload files with names containing HTML tags. As HTML tags can include JavaScript code, this can be used to execute JavaScript code in the context of the user. This is a self-injection style attack and relies on a user uploading the malicious file themselves and it impact only them, not other users. A user might be social engineered into running this to launch a phishing attack. Nevertheless, this breaks the expected security restrictions in place by the application. This issue has been addressed in version 0.32.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
