• CVE-2026-102527: 0.19% estimated exploitation activity in the next 30 days; percentile 8.23 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Vendor: Nuxt Product: Nuxt OG Image Version: 6.2.5 Description: Due to the specifics of caching and key generation in the Open Graph image cache created by the module, an unauthenticated attacker can modify the content of the image (for example, the title parameter) that is delivered to the user. Impact: Content Spoofing Vulnerable component: route /og/d/.png Exploitation conditions: Access to the application Mitigation: Upgrade to 6.7.2 and set a sufficiently secure secret in config ogImage Researcher: Dmitry Vanin (Positive Technologies) Research During the previous vulnerability research, it was discovered that version 6.2.5 changed the mechanism for generating cache indexes; it now takes into account the parameters passed during image generation. However, the image is still generated from data transmitted to the attacker. Listing 1. New code for generating indexes in cache In this case, basePath is obtained from the path parameter, resolvedOptions are the normalized settings of…

# Patch Next advisory brief: CVE-2026-102527

Advisory: Nuxt OG Image cache poisoning through derivable cache keys on unsigned dynamic image routes
IDs: CVE-2026-102527, GHSA-2x6f-rp82-ppmj
Record: https://patchnext.com/advisories/cve-2026-102527 (revision 4, source checked 26 Oct 2026, 13:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: nuxt-og-image 6.7.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm nuxt-og-image: affected >= 6.2.5, < 6.7.0; fixed in 6.7.0

## Suggested inspection (read-only)
- `npm ls nuxt-og-image --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on nuxt-og-image.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-2x6f-rp82-ppmj (GitHub-reviewed advisory GHSA-2x6f-rp82-ppmj lists affected ranges: npm nuxt-og-image >=6.2.5 <6.7.0)
