2DescriptionCVE.org
surya 0.22.1 screenshot server contains an unauthenticated arbitrary file read vulnerability in the /info, /page, and /process routes that accept raw file_path parameters. Attackers can read any image or PDF file on the host by supplying arbitrary file paths to Image.open or pypdfium2.PdfDocument, obtaining rendered contents as base64 and using /info as an existence oracle.
AnalysisAI
Unauthenticated arbitrary file read in the surya 0.22.1 screenshot server allows any network-reachable attacker to exfiltrate image and PDF files from the host filesystem by supplying attacker-controlled paths to three unprotected HTTP routes. The /info, /page, and /process endpoints pass raw file_path parameters directly to Pillow's Image.open and pypdfium2.PdfDocument, returning rendered file contents as base64-encoded HTTP responses. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The surya screenshot server (screenshot_app.py) must be running and reachable by the attacker over the network - this server is an optional component not started during normal library usage, so it must have been deliberately launched. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) accurately reflects the mechanics: zero-complexity, zero-authentication network exploitation with full confidentiality impact on the vulnerable system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch version is identified from the available data; the issue is tracked at https://github.com/datalab-to/surya/issues/518 and should be monitored for an upstream fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems running surya version 0.22.1 and immediately restrict network access to the vulnerable endpoints (/info, /page, /process) through firewall rules, network segmentation, or service disablement; concurrently begin reviewing access logs for signs of exploitation. …
