SCA: security update for @opennextjs/cloudflare (GHSA-2vc4-c4r6-p6v6)

high Tenable Cloud Security Plugin ID 474690

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- OpenNext Cloudflare is an open Next.js adapter for Cloudflare. From 0.3.0 until 1.20.2, applications that
enable enableCacheInterception, rely on middleware for access control, and have a matching cached
protected route process encoded pathnames inconsistently between middleware matching and cache lookup. An
unauthenticated attacker can use a percent-encoded pathname that does not match authorization middleware
but decodes to the cache key of a protected route, causing cached content to be returned without
authorization. Malformed encodings can also be partially decoded, allowing cache lookup to continue with a
pathname that middleware did not evaluate consistently. This issue is fixed in version 1.20.2.
(CVE-2026-100409)

Solution

Update the @opennextjs/cloudflare library and its related packages to version 1.20.2 or later.
