DescriptionCVE.org

redis-parser through 3.0.0 fails to validate the multi-bulk length value in RESP protocol parsing, allowing attackers to trigger an uncaught RangeError by supplying an excessively large declared length. A malicious or compromised Redis endpoint can deliver a crafted RESP header with a length above 2^32-1 to crash the Node.js client process.

AnalysisAI

Denial of service in NodeRedis redis-parser through 3.0.0 lets a hostile or hijacked Redis endpoint crash the Node.js client process by returning a crafted RESP multi-bulk header whose declared length exceeds 2^32-1, triggering an uncaught RangeError during parsing. The flaw is reachable by unauthenticated remote attackers (CVSS 4.0 AV:N/AC:L/AT:N/PR:N/UI:N) but its impact is strictly availability (VA:H) - no confidentiality, integrity, or scope impact - so a malicious server, a compromised legitimate Redis instance, or an on-path injector in the RESP response stream can only take down the parsing process. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the victim Node.js process using redis-parser <=3.0.0 parse RESP data from an attacker-controlled source: a malicious Redis server, a compromised/hijacked legitimate Redis instance, or an on-path attacker injecting into the RESP response stream. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (8.7, AV:N/AC:L/AT:N/PR:N/UI:N) rates this HIGH, but the impact is strictly availability (VA:H) with no confidentiality or integrity effect - this is a pure denial-of-service crash of the Node.js client process, consistent with CWE-1284 (improper validation of a specified quantity in input). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch identified at time of analysis: the references for CVE-2026-97057 are the upstream issue tracker and source-code permalinks rather than a tagged fixed release, so there is no authoritative version number to upgrade to and none should be assumed. … Detailed patch versions, workarounds, and compensating controls in full report.
