Frequently Asked Questions

CVE-2026-77814: Technical Details & Impact

What is CVE-2026-77814 and which software versions are affected?

CVE-2026-77814 is a path traversal vulnerability (CWE-22) in the infinite-image-browsing application, including its Stable Diffusion WebUI extension. The flaw allows unauthenticated remote attackers to read files outside intended directories due to improper path validation in the is_path_trusted function. All versions from 0 through 1.8.0 (inclusive) are affected. Vulnerable files include scripts/iib/api.py and scripts/iib/tool.py. See the official CVE record. Note: This vulnerability only impacts infinite-image-browsing and its extension, not other unrelated software.

How severe is CVE-2026-77814?

CVE-2026-77814 has a CVSS v4.0 base score of 8.7 (HIGH) and a CVSS v3.1 score of 7.5 (HIGH). The vulnerability allows disclosure of restricted files on the host filesystem, impacting confidentiality but not integrity or availability. The attack requires no authentication or user interaction and can be exploited over the network. Note: Severity ratings are based on published CVSS vectors; always consult the latest advisories for updates.

What is the root cause of CVE-2026-77814?

The vulnerability is caused by improper path validation in the is_path_trusted function within scripts/iib/api.py. The function checks if a requested path starts with an allowed parent path but fails to append a path separator, allowing sibling directories with similar names to bypass restrictions. Additionally, reliance on os.path.normpath does not resolve symlinks, enabling attackers to use symlinks to access files outside the intended directory. Note: This root cause is specific to infinite-image-browsing ≤ 1.8.0.

How can organizations mitigate or remediate CVE-2026-77814?

To mitigate CVE-2026-77814, upgrade infinite-image-browsing to a version containing the fix committed in pull request #969 (commit 4057a624c7a23a36f0b4dc6a545b40767d602450). If immediate patching is not possible, avoid exposing the application to untrusted networks, enable access control explicitly, and place the application behind an authenticating reverse proxy. Restrict network access to trusted hosts only. Note: These mitigations reduce risk but do not fully eliminate it until the patch is applied.

Where can I find official references and technical details for CVE-2026-77814?

Official references for CVE-2026-77814 include the CVE record, GitHub Issue #968, and GitHub Pull Request #969 (fix). These sources provide technical details, root cause analysis, and remediation steps. Note: Always consult the latest advisories for updates.

Mitigation & Response with IONIX

How can IONIX help organizations detect and mitigate exposure to CVE-2026-77814?

IONIX's External Exposure Management platform continuously maps your entire external attack surface, including cloud instances, third-party platforms, and shadow IT. For CVE-2026-77814, IONIX identifies all assets running infinite-image-browsing ≤ 1.8.0, confirms which are externally reachable, and validates exploitability using safe, non-intrusive test payloads. Results are prioritized and routed to ticketing and SIEM tools for rapid remediation. Note: IONIX's mitigation workflow is most effective for organizations with dynamic, internet-facing environments; internal-only deployments may require additional controls.

What is IONIX's Live Exposure Defense and how does it support zero-day response?

Live Exposure Defense is IONIX's commitment to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation completed within the same window. For zero-days like CVE-2026-77814, IONIX's agentic workflow discovers, validates, and prioritizes exposures at machine speed, enabling security teams to mitigate risks before attackers can exploit them.

CVE-2026-77814 – Path Traversal / Arbitrary File Read – infinite-image-browsing ≤ 1.8.0

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

Summary

CVE-2026-77814 is a path traversal vulnerability (CWE-22) in infinite-image-browsing, an image/video management application that also ships as a Stable Diffusion WebUI extension. The flaw lies in the is_path_trusted access-control function and allows an unauthenticated remote attacker to read files outside the directories the application is supposed to restrict access to. The issue carries a CVSS v4.0 base score of 8.7 (HIGH).

Technical details

  • Root cause: is_path_trusted in scripts/iib/api.py validates requested paths using path.startswith(parent_path) without appending a path separator, so a sibling directory whose name merely begins with an allowed path (e.g. /data/images_private) is incorrectly treated as trusted when /data/images is the allowed path.
  • The check also relies on os.path.normpath, which does not resolve symlinks, so a symlink placed inside an otherwise-allowed directory can be used to point outside it.
  • Attack vector: network, no authentication or user interaction required; the attacker sends a crafted request to the application’s file-serving endpoint (used by FileResponse).
  • Trigger conditions: the vulnerable code path is reachable when access control is enabled (IIB_ACCESS_CONTROL set to "enable") or when the application is exposed over the network (e.g. via share, ngrok, listen, or server_name deployment options). Note that in default standalone configuration, access control is disabled entirely, which independently exposes all files without authentication.
  • Impact: disclosure of restricted files on the host filesystem (confidentiality impact only; no impact on integrity or availability per the published vector).

Affected software

  • infinite-image-browsing (zanllp/infinite-image-browsing), including its Stable Diffusion WebUI extension form: versions 0 through 1.8.0 (inclusive).
  • Vulnerable files: scripts/iib/api.py, scripts/iib/tool.py.

Severity

  • 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
  • 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

Mitigation and recommended actions

  • Immediate: upgrade to a version containing the fix committed in 4057a624c7a23a36f0b4dc6a545b40767d602450 (merged via pull request #969), which resolves the path-validation flaw for versions beyond 1.8.0.
  • If patching is not immediately possible: avoid exposing the application to untrusted networks (do not use share, ngrok, listen, or server_name options without additional protections); ensure access control is explicitly enabled rather than relying on defaults; place the application behind an authenticating reverse proxy and restrict network access to trusted hosts only.

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.
