CVE-2026-34404: CWE-400: Uncontrolled Resource Consumption in nuxt-modules og-image
Nuxt OG Image generates OG Images with Vue templates in Nuxt. Prior to version 6.2.5, the image‑generation component by the URI: /_og/d/ (and, in older versions, /og-image/) contains a Denial of Service (DoS) vulnerability. The issue arises because there is no restriction on the width and height parameters of the generated image. The vulnerability was reproduced using the standard configuration and the default templates. This issue has been patched in version 6.2.5.
AI Analysis
Technical Summary
The nuxt-modules og-image component generates Open Graph images using Vue templates in Nuxt. Versions before 6.2.5 expose a DoS vulnerability via the image generation URI (/ _og/d/ or /og-image/ in older versions) due to lack of validation on width and height parameters. Attackers can specify excessively large dimensions, causing uncontrolled resource consumption and potential service disruption. The vulnerability is tracked as CWE-400 (Uncontrolled Resource Consumption) and has a CVSS 4.0 base score of 6.9 (medium severity). The issue was confirmed with default templates and standard configuration. A patch fixing this vulnerability was released in version 6.2.5.
Potential Impact
Exploitation of this vulnerability can lead to Denial of Service by exhausting server resources through generation of overly large images. This can disrupt availability of the affected service. There is no indication of privilege escalation, data disclosure, or code execution. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade the nuxt-modules og-image component to version 6.2.5 or later, where the vulnerability is patched. Since this is not a cloud service, users must apply the update themselves. Patch status is confirmed by the vendor advisory stating the fix is included in version 6.2.5.
