An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-2293 exists.\n\nAffected packages and fixed versions:\n- @nestjs/platform-fastify (npm): affected all versions; fixed in 11.1.14\n- @nestjs/platform-fastify (npm): affected all versions; fixed in 11.1.14\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-2293/ (Markdown: https://insights.sbomify.com/CVE-2026-2293/index.md)","id":"CVE-2026-2293","markdown":"https://insights.sbomify.com/CVE-2026-2293/index.md","name":"CVE-2026-2293","record":{"aliases":["GHSA-r4wm-x892-vjmx"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"NestJS framework","requires_auth":"none","summary":"Attackers can bypass authentication and authorization middleware in NestJS applications using Fastify if path normalization is enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[{"product":"nest","vendor":"nestjs"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-551","name":"Incorrect Behavior Order: Authorization Before Parsing and Canonicalization"},{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"A NestJS application using @nestjs/platform-fastify can allow bypass of authentication/authorization middleware when Fastify path-normalization options are enabled.\n\nThis issue affects nest.Js: 11.1.13.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"NestJS 11.1.13 - Lack of data validation allowing authentication/authorization bypass","id":"CVE-2026-2293","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Missing authorization in UiPress lite | Effortless custom dashboards, admin themes and pages","id":"CVE-2026-2294"},"packages":[{"ecosystem":"npm","fixed":["11.1.14"],"introduced":["0"],"last_affected":[],"package":"@nestjs/platform-fastify","purl":null,"source":"GHSA-r4wm-x892-vjmx"},{"ecosystem":"npm","fixed":["11.1.14"],"introduced":["0"],"last_affected":[],"package":"@nestjs/platform-fastify","purl":"pkg:npm/%40nestjs/platform-fastify","source":"GHSA-r4wm-x892-vjmx"}],"prev":{"headline":"Morkva UA Shipping \u003c= 1.7.9 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Weight, kg' Field","id":"CVE-2026-2292"},"products":["nest.js"],"published":"2026-02-27","related":[{"cvss_score":8.7,"headline":"Nest Fastify HEAD Request Middleware Bypass","id":"CVE-2026-33011","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":7.5,"headline":"Nest: DoS via Recursive handleData in JsonSocket (TCP Transport)","id":"CVE-2026-40879","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":6.9,"headline":"Nest has a Fastify URL Encoding Middleware Bypass (TOCTOU)","id":"CVE-2025-69211","kev_date_added":null,"published":"2025-12-29"},{"cvss_score":6.3,"headline":"@nestjs/core Improperly Neutralizes Special Elements in Output Used by a Downstream Component ('Injection')","id":"CVE-2026-35515","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":5.5,"headline":"nest allows a remote attacker to execute arbitrary code via the Content-Type header","id":"CVE-2024-29409","kev_date_added":null,"published":"2025-03-14"},{"cvss_score":3.7,"headline":"@nestjs/core vulnerable to Information Exposure via StreamableFile pipe","id":"CVE-2023-26108","kev_date_added":null,"published":"2023-03-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-15","vendors":["nest.js"]},"summary":"Attackers can bypass authentication and authorization middleware in NestJS applications using Fastify if path normalization is enabled.","url":"https://insights.sbomify.com/CVE-2026-2293/"}
