Privilege escalation in Stirling-PDF before 2.9.0 allows any authenticated ROLE_USER to obtain the privileged STIRLING-PDF-BACKEND-API-USER internal service account API key through the pipeline subrequest mechanism, then impersonate that account to bypass rate limits and query sensitive monitoring endpoints such as /api/v1/info/requests/all and /api/v1/info/load/all. The root cause is PipelineProcessor.java injecting the static internal service account key into pipeline subrequests rather than the requesting user's own key, making it retrievable via /api/v1/user/get-api-key. No public exploit or CISA KEV listing exists at time of analysis; vendor-released patch v2.9.0 resolves the issue.
Stored cross-site scripting in Stirling-PDF prior to version 2.0.0 allows an attacker to embed JavaScript payloads inside PDF metadata fields (Title or Author) that execute in a victim's browser session when the user triggers the 'Get Info' workflow. The vulnerable template at get-info-on-pdf.html injects unsanitized metadata directly into the DOM via innerHTML, enabling session token theft and arbitrary page content manipulation against any user who processes a crafted PDF on a shared instance. No public exploit has been identified at time of analysis, and the vendor has shipped a complete fix in the major v2.0.0 release.
Server-side request forgery in Stirling-PDF's POST /api/v1/convert/url/pdf endpoint allows unauthenticated remote attackers to exfiltrate cloud metadata and internal network resources by supplying a URL to an attacker-controlled page containing embedded resource references (e.g., img tags targeting 169.254.169.254). The endpoint was deliberately excluded from the SSRF protections applied to three sibling conversion endpoints, creating an uneven security boundary; WeasyPrint, the underlying rendering subprocess, fetches all embedded resources with no per-resource SSRF filtering, causing internal HTTP responses to be embedded verbatim into the returned PDF. No public exploit code or CISA KEV listing has been identified at time of analysis, but the attack requires no authentication and no special configuration, making any network-exposed Stirling-PDF instance a viable target.
Stirling-PDF, a locally hosted web application for PDF operations, contains a path traversal vulnerability in the /api/v1/convert/markdown/pdf endpoint that allows authenticated users to write arbitrary files outside the intended directory. Versions prior to 2.5.2 are affected, enabling attackers to overwrite writable files with the privileges of the stirlingpdfuser process account, compromising data integrity and potentially availability. The vulnerability has been patched in version 2.5.2, and while CVSS rates it 8.1 (High), authentication is required which reduces immediate risk.
Stored cross-site scripting in Stirling-PDF's /get-info-on-pdf endpoint allows attacker-controlled JavaScript to execute in any user's browser when they view metadata of a crafted PDF file. All versions prior to 2.0.0 are affected; the CVSS scope change (S:C) indicates injected scripts operate within the application's browser origin, enabling session hijacking or unauthorized actions. No public exploit code has been identified at time of analysis and this vulnerability has not been listed in CISA KEV.
Reflected cross-site scripting (XSS) in Stirling-PDF versions before 2.0.0 allows unauthenticated remote attackers to execute arbitrary JavaScript in a victim's browser by uploading a file with a malicious filename containing script code. The vulnerability affects multiple file upload endpoints that render user-supplied filenames directly into HTML via unsafe DOM manipulation methods without sanitization. Attack requires user interaction (victim must upload the crafted file), limiting real-world impact. No public exploit code or active exploitation has been identified at time of analysis.
Stirling-PDF version 2.7.3 fails to sanitize HTML content from email bodies in the /api/v1/convert/eml/pdf endpoint when the downloadHtml=true parameter is set, allowing unauthenticated remote attackers to inject and execute arbitrary JavaScript code. An attacker can craft a malicious email that, when processed by a Stirling-PDF user through the 'Download HTML intermediate file' feature, executes JavaScript in the user's browser context with access to local data and session tokens. Proof-of-concept code has been demonstrated, and the vendor released version 2.8.0 to address the vulnerability.
Stirling-PDF versions 2.1.5 through 2.5.1 are vulnerable to resource exhaustion denial of service through the watermark API endpoint, where authenticated users can supply extreme values for fontSize and widthSpacer parameters to crash the server. A proof-of-concept exists according to SSVC data, and the vendor has released patched version 2.5.2 to resolve the issue.
Stirling-PDF is a locally hosted web application that performs various operations on PDF files. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
