NestJS
Monthly
Remote attackers can crash Nest.js applications (versions prior to 11.1.19) by sending approximately 47 KB of fragmented JSON messages within a single TCP frame, triggering a call stack overflow. The handleData() function's recursive processing of small valid JSON messages causes stack exhaustion before maxBufferSize limits are enforced, resulting in RangeError and denial of service. No authentication required (CVSS AV:N/PR:N). Vendor patch released in version 11.1.19. EPSS data not available; no confirmed active exploitation (not in CISA KEV).
A NestJS application using @nestjs/platform-fastify can allow bypass of authentication/authorization middleware when Fastify path-normalization options are enabled. This issue affects nest.Js: 11.1.13.
Nest is a framework for building scalable Node.js server-side applications. Rated critical severity (CVSS 9.4), this vulnerability is no authentication required, low attack complexity. Public exploit code available and EPSS exploitation probability 22.1%.
File Upload vulnerability in nestjs nest v.10.3.2 allows a remote attacker to execute arbitrary code via the Content-Type header. Rated medium severity (CVSS 5.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Versions of the package @nestjs/core before 9.0.5 are vulnerable to Information Exposure via the StreamableFile pipe. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
