CVE-2026-6410 (GCVE-0-2026-6410)
Vulnerability from nvd – Published: 2026-04-16 13:29 – Updated: 2026-04-16 14:19

Title
@fastify/static vulnerable to path traversal in directory listing
Summary
@fastify/static versions 8.0.0 through 9.1.0 allow path traversal when directory listing is enabled via the list option. The dirList.path() function resolves directories outside the configured static root using path.join() without a containment check. A remote unauthenticated attacker can obtain directory listings for arbitrary directories accessible to the Node.js process, disclosing directory and file names. File contents are not disclosed. Upgrade to @fastify/static 9.1.1 to fix this issue. As a workaround, disable directory listing by removing the list option from the plugin configuration.

CVE-2026-6414 (GCVE-0-2026-6414)
Vulnerability from nvd – Published: 2026-04-16 13:09 – Updated: 2026-04-16 13:48

Title
@fastify/static vulnerable to route guard bypass via encoded path separators
Summary
@fastify/static versions 8.0.0 through 9.1.0 decode percent-encoded path separators (%2F) before filesystem resolution, while Fastify's router treats them as literal characters. This mismatch allows attackers to bypass route-based middleware or guards that protect files served by @fastify/static. For example, a route guard on a protected path can be circumvented by encoding the path separator in the URL. Upgrade to @fastify/static 9.1.1 to fix this issue. There are no workarounds.

Title
@fastify/static vulnerable to path traversal in directory listing
Summary
@fastify/static versions 8.0.0 through 9.1.0 allow path traversal when directory listing is enabled via the list option. The dirList.path() function resolves directories outside the configured static root using path.join() without a containment check. A remote unauthenticated attacker can obtain directory listings for arbitrary directories accessible to the Node.js process, disclosing directory and file names. File contents are not disclosed. Upgrade to @fastify/static 9.1.1 to fix this issue. As a workaround, disable directory listing by removing the list option from the plugin configuration.

CVE-2026-6414 (GCVE-0-2026-6414)
Vulnerability from cvelistv5 – Published: 2026-04-16 13:09 – Updated: 2026-04-16 13:48

Title
@fastify/static vulnerable to route guard bypass via encoded path separators
Summary
@fastify/static versions 8.0.0 through 9.1.0 decode percent-encoded path separators (%2F) before filesystem resolution, while Fastify's router treats them as literal characters. This mismatch allows attackers to bypass route-based middleware or guards that protect files served by @fastify/static. For example, a route guard on a protected path can be circumvented by encoding the path separator in the URL. Upgrade to @fastify/static 9.1.1 to fix this issue. There are no workarounds.
