CVE-2026-5038 1 Expressjs 1 Multer 2026-06-16 5.3 Medium
Impact: multer versions 2.0.0-alpha.1 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service when using diskStorage. Aborted or malformed multipart uploads leave orphaned partial files on disk because the Readable.pipe() call does not propagate the stream destroy signal to the underlying fs.WriteStream. An attacker can exhaust disk space by triggering many aborted uploads, with no application bug required. Patches: Users should upgrade to multer 2.2.0 (2.x line) or 3.0.0-alpha.2 (3.x prerelease). Both versions track in-flight write streams and clean them up on the abort path. Workarounds: None.
CVE-2026-5079 1 Expressjs 1 Multer 2026-06-16 7.5 High
Impact: multer versions 1.0.0 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service via deeply nested field names in multipart form data. The append-field dependency parses bracket notation in field names with no limit on nesting depth, allowing an attacker to force allocation of deeply nested object structures that consume CPU and memory. A single HTTP request with a crafted multipart body is sufficient to exploit this. Patches: Users should upgrade to multer 2.2.0 (2.x line) or 3.0.0-alpha.2 (3.x prerelease) and configure the new limits.fieldNestingDepth option to the minimum depth their application requires. Workarounds: Set limits.fields to a reasonable value to reduce the number of fields an attacker can send per request. This does not fully mitigate the issue but limits the impact.
CVE-2026-2359 1 Expressjs 1 Multer 2026-04-17 7.5 High
Multer is a node.js middleware for handling `multipart/form-data`. A vulnerability in Multer prior to version 2.1.0 allows an attacker to trigger a Denial of Service (DoS) by dropping connection during file upload, potentially causing resource exhaustion. Users should upgrade to version 2.1.0 to receive a patch. No known workarounds are available.
CVE-2026-3520 1 Expressjs 1 Multer 2026-04-17 7.5 High
Multer is a node.js middleware for handling `multipart/form-data`. A vulnerability in Multer prior to version 2.1.1 allows an attacker to trigger a Denial of Service (DoS) by sending malformed requests, potentially causing stack overflow. Users should upgrade to version 2.1.1 to receive a patch. No known workarounds are available.
CVE-2026-3304 1 Expressjs 1 Multer 2026-04-16 7.5 High
Multer is a node.js middleware for handling `multipart/form-data`. A vulnerability in Multer prior to version 2.1.0 allows an attacker to trigger a Denial of Service (DoS) by sending malformed requests, potentially causing resource exhaustion.

CVE-2024-9266 1 Expressjs 1 Express 2026-04-15 4.7 Medium
URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Express. This vulnerability affects the use of the Express Response object. This issue impacts Express: from 3.4.5 before 4.0.0.
CVE-2025-13466 1 Expressjs 1 Body-parser 2026-04-15 5.3 Medium
body-parser 2.2.0 is vulnerable to denial of service due to inefficient handling of URL-encoded bodies with very large numbers of parameters. An attacker can send payloads containing thousands of parameters within the default 100KB request size limit, causing elevated CPU and memory usage. This can lead to service slowdown or partial outages under sustained malicious traffic. This issue is addressed in version 2.2.1.
CVE-2024-10491 2 Expressjs, Openjsf 2 Express, Express 2026-01-09 4 Medium
A vulnerability has been identified in the Express response.links function, allowing for arbitrary resource injection in the Link header when unsanitized data is used. The issue arises from improper sanitization in `Link` header values, which can allow a combination of characters like `,`, `;`, and `<>` to preload malicious resources. This vulnerability is especially relevant for dynamic parameters.
CVE-2024-51999 1 Expressjs 1 Express 2025-12-02 N/A
** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. Reason: This candidate was issued in error and is not a valid vulnerability. Notes: All references and descriptions in this candidate have been removed to prevent accidental usage.
CVE-2017-16136 1 Expressjs 1 Method-override 2024-11-21 N/A
method-override is a module used by the Express.js framework to let you use HTTP verbs such as PUT or DELETE in places where the client doesn't support it. method-override is vulnerable to a regular expression denial of service vulnerability when specially crafted input is passed in to be parsed via the X-HTTP-Method-Override header.
CVE-2024-47178 1 Expressjs 1 Basic-auth-connect 2024-11-15 5.3 Medium
basic-auth-connect is Connect's Basic Auth middleware in its own module. basic-auth-connect < 1.1.0 uses a timing-unsafe equality comparison that can leak timing information. This issue has been fixed in basic-auth-connect 1.1.0.
CVE-2024-45590 3 Expressjs, Openjsf, Redhat 13 Body-parser, Body-parser, Advanced Cluster Security and 10 more 2024-09-20 7.5 High
body-parser is Node.js body parsing middleware. body-parser <1.20.3 is vulnerable to denial of service when url encoding is enabled. A malicious actor using a specially crafted payload could flood the server with a large number of requests, resulting in denial of service. This issue is patched in 1.20.3.
