AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Network-reachable WebCrypto operation, no auth or interaction (PR:N/UI:N/AC:L); integer overflow yields a process crash, so availability-only (A:H, C:N/I:N).

AnalysisAI
Denial of service in Node.js 26.x (fixed in 26.3.1) arises from an unguarded integer overflow when computing WebCrypto cipher output buffer lengths, allowing remote attackers to crash a process that performs SubtleCrypto encrypt/decrypt operations on attacker-influenced data. Rated High by the Node.js project (CVSS 7.5, availability-only impact). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Technical ContextAI
The flaw lives in Node.js's WebCrypto (Web Crypto API / SubtleCrypto) implementation, the standards-based cryptographic interface exposed through globalThis.crypto.subtle. The root cause is CWE-190 (Integer Overflow or Wraparound): the code computing the output length for a cipher operation was not properly bounds-checked, so a large or crafted input size can cause the length calculation to wrap around. The fix commit (98fbc89211, 'crypto: guard WebCrypto cipher output length', by Filip Skokan) adds an explicit guard on that computed length. Because this is the runtime's own crypto layer rather than a third-party library, any application calling subtle.encrypt/decrypt with externally-controlled buffer sizes inherits the exposure.
RemediationAI
Vendor-released patch: Node.js 26.3.1 - upgrade from 26.x to 26.3.1 (or the corresponding patched build on your release line as listed in the Node.js June 2026 security release advisory at https://nodejs.org/en/blog/vulnerability/june-2026-security-releases). Release notes: https://github.com/nodejs/node/releases/tag/v26.3.1 (fix commit 98fbc89211). If immediate upgrade is not possible, the practical compensating control is to avoid passing untrusted or unbounded input lengths into crypto.subtle.encrypt/decrypt - validate and cap the size of any externally-supplied ciphertext/plaintext before handing it to WebCrypto, or route such operations through Node's classic crypto module where appropriate; the trade-off is added input-validation code and possible API changes in your application. Restricting or rate-limiting endpoints that expose WebCrypto operations to untrusted callers reduces crash exposure but does not eliminate the underlying overflow.
