Frequently Asked Questions

CVE-2026-85687: Surya Screenshot Server Vulnerability

What is CVE-2026-85687 and which software is affected?

CVE-2026-85687 is an unauthenticated arbitrary file read vulnerability (CWE-73) in the Surya screenshot server (PyPI package surya-ocr), maintained by datalab-to. All versions up to and including 0.22.1 are affected. The flaw allows any network-based attacker to retrieve image and PDF files from the host filesystem without authentication, with a CVSS v4.0 base score of 8.7 (High) and CVSS v3.1 base score of 7.5 (High). Note: No fixed release is available as of September 4, 2026; monitor the upstream repository for updates. Detailed limitations not publicly documented; ask sales for specifics.

What are the recommended mitigations for CVE-2026-85687?

Until a patched release is available, do not expose the Surya screenshot server (default port 8504) to untrusted networks or the public internet. Bind the service to localhost instead of 0.0.0.0, place it behind an authenticating reverse proxy or VPN, and restrict accessible file paths using filesystem permissions or containerization. Monitor logs for suspicious requests to /info, /page, and /process endpoints. Note: These mitigations reduce risk but do not fully eliminate the vulnerability until an upstream patch is applied.

How can I check if my organization is exposed to CVE-2026-85687?

IONIX offers a free exposure report that maps all assets using the Surya screenshot server, identifies potentially exposed assets to CVE-2026-85687, and confirms which assets are verifiably exploitable. Request a scan at ionix.io/request-a-scan. Note: The report depends on accurate asset discovery; assets not visible from the external attack surface may not be included.

IONIX External Exposure Management & Zero-Day Response

How does IONIX detect and validate exposures to new zero-day vulnerabilities like CVE-2026-85687?

IONIX continuously analyzes dozens of threat intelligence feeds using agentic technology to detect new CVEs, proof-of-concept code, and exploit kits. The platform applies AI to proactively evaluate exploitability, then maps every internet-facing asset, including cloud instances, third-party platforms, and shadow IT. IONIX filters vulnerabilities by attacker-centric criteria (reachability, authentication requirements, active exploitation) and transforms PoCs into safe, non-intrusive test payloads for validation. This process ensures rapid, targeted validation of exposures. Note: Validation is limited to assets discoverable from the external attack surface; internal-only assets require additional controls.

What is Live Exposure Defense and how does it help with zero-day threats?

Live Exposure Defense is an IONIX capability that commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation inside the same window. This enables organizations to respond to zero-day threats like CVE-2026-85687 before attackers can exploit them. Note: The 12-hour SLA applies to assets visible from the external attack surface; internal assets may require additional validation steps.

How does IONIX prioritize and mitigate validated exposures?

IONIX routes validated findings through integrations with ticketing (Jira, ServiceNow), SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This workflow shortens mean time to remediation (MTTR) and empowers teams to act quickly. Note: Remediation effectiveness depends on integration with existing IT and security processes.

New CVE Detected

CVE-2026-85687 – Unauthenticated Arbitrary File Read – Surya Screenshot Server ≤0.22.1

Be the first to know when new zero-days emerge:

Summary

CVE-2026-85687 is an unauthenticated arbitrary file read vulnerability (CWE-73: External Control of File Name or Path) affecting the screenshot server component of Surya (PyPI package surya-ocr), an open-source OCR/document layout analysis tool maintained by datalab-to. The flaw allows any network-based attacker to retrieve image and PDF files from the host filesystem without authentication. The issue carries a CVSS v4.0 base score of 8.7 (High) / CVSS v3.1 base score of 7.5 (High).

Technical details

  • Root cause: The Flask-based screenshot server accepts a user-supplied file_path parameter and passes it, without validation or sanitization, directly into internal file-processing helper functions (_page_count() and _render_page()). No containment or workspace restriction is applied to the supplied path.
  • Trigger conditions: The server listens on 0.0.0.0:8504 by default with no authentication decorator on any route, meaning it is reachable from the network without credentials whenever exposed.
  • Attack vector: Remote/network — an attacker sends crafted requests to the /info, /page, or /process endpoints, supplying an arbitrary file path instead of an expected in-workspace file reference.
  • Impact: Unauthenticated disclosure of arbitrary image and PDF files on the host, including files outside the intended workspace directory; the /info endpoint can also be used to enumerate whether specific file paths exist on the system, aiding further reconnaissance. There is no reported impact to integrity or availability — the vulnerability is limited to confidentiality (file read).

Affected software

  • Product: Surya screenshot server (PyPI package surya-ocr), vendor datalab-to
  • Affected versions: All versions through 0.22.1 (0 – 0.22.1)

Severity

  • CVSS v3.1: 7.5 (High) — CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
  • CVSS v4.0: 8.7 (High) — CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: As of publication, no fixed release has been assigned in the upstream tracking issue; monitor the datalab-to/surya repository for a patched release and upgrade as soon as one is available.
  • Workarounds / network mitigations (until patched):
    • Do not expose the Surya screenshot server (default port 8504) directly to untrusted networks or the public internet; bind it to localhost/127.0.0.1 instead of 0.0.0.0.
    • Place the service behind an authenticating reverse proxy or VPN, since the application itself performs no authentication on the /info, /page, or /process routes.
    • Restrict the file paths accessible to the service (e.g., via filesystem permissions, containerization, or a chroot/jail) so that even if file_path is manipulated, no sensitive files outside the intended workspace can be reached.
    • Monitor logs for requests to /info, /page, and /process containing path traversal sequences (../) or absolute paths outside the expected document directory.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
