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-2023-26113 exists.\n\nAffected packages and fixed versions:\n- collection.js (npm): affected all versions; fixed in 6.8.1\n- collection.js (npm): affected all versions; fixed in 6.8.1\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-2023-26113/ (Markdown: https://insights.sbomify.com/CVE-2023-26113/index.md)","id":"CVE-2023-26113","markdown":"https://insights.sbomify.com/CVE-2023-26113/index.md","name":"CVE-2023-26113","record":{"aliases":["GHSA-47pj-q2vm-46xc"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript utility library","requires_auth":"none","summary":"Prototype pollution in collection.js allows attackers to modify object prototypes, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"collection.js","vendor":"collection.js_project"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Versions of the package collection.js before 6.8.1 are vulnerable to Prototype Pollution via the extend function in Collection.js/dist/node/iterators/extend.js.","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":"Collection.js vulnerable to Prototype Pollution","id":"CVE-2023-26113","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2023"},"n_packages":2,"n_references":5,"next":{"headline":"code-server vulnerable to Missing Origin Validation in WebSockets","id":"CVE-2023-26114"},"packages":[{"ecosystem":"npm","fixed":["6.8.1"],"introduced":["0"],"last_affected":[],"package":"collection.js","purl":null,"source":"GHSA-47pj-q2vm-46xc"},{"ecosystem":"npm","fixed":["6.8.1"],"introduced":["0"],"last_affected":[],"package":"collection.js","purl":"pkg:npm/collection.js","source":"GHSA-47pj-q2vm-46xc"}],"prev":{"headline":"configobj ReDoS exploitable by developer using values in a server-side configuration file","id":"CVE-2023-26112"},"products":["collection.js"],"published":"2023-03-18","related":[],"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":"2025-02-26","vendors":["n/a"]},"summary":"Prototype pollution in collection.js allows attackers to modify object prototypes, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2023-26113/"}
