An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-0748 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- post-loader (npm): affected from 0.0.0; no fix listed\n- post-loader (npm): affected from 0.0.0; no fix listed\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-2022-0748/ (Markdown: https://insights.sbomify.com/CVE-2022-0748/index.md)","id":"CVE-2022-0748","markdown":"https://insights.sbomify.com/CVE-2022-0748/index.md","name":"CVE-2022-0748","record":{"aliases":["GHSA-66ww-999q-mffq","SNYK-JS-POSTLOADER-2403737"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"npm markdown parser","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript code by providing malicious markdown input to the post-loader library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"post-loader","vendor":"post-loader_project"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The package post-loader from 0.0.0 are vulnerable to Arbitrary Code Execution which uses a markdown parser in an unsafe way so that any javascript code inside the markdown input files gets evaluated and executed.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Arbitrary Code Execution","id":"CVE-2022-0748","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2022"},"n_packages":2,"n_references":1,"next":{"headline":"Deserialization of Untrusted Data","id":"CVE-2022-0749"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0.0.0"],"last_affected":[],"package":"post-loader","purl":null,"source":"GHSA-66ww-999q-mffq"},{"ecosystem":"npm","fixed":[],"introduced":["0.0.0"],"last_affected":[],"package":"post-loader","purl":"pkg:npm/post-loader","source":"GHSA-66ww-999q-mffq"}],"prev":{"headline":"Infographic Maker - iList \u003c 4.3.8 - Unauthenticated SQL Injection","id":"CVE-2022-0747"},"products":["post-loader"],"published":"2022-03-17","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Attackers can execute arbitrary JavaScript code by providing malicious markdown input to the post-loader library.","url":"https://insights.sbomify.com/CVE-2022-0748/"}
