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-2025-25977 exists.\n\nAffected packages and fixed versions:\n- canvg (npm): affected all versions; fixed in 3.0.11\n- canvg (npm): affected all versions; fixed in 3.0.11\n- canvg (npm): affected from 4.0.0; fixed in 4.0.3\n- canvg (npm): affected from 4.0.0; fixed in 4.0.3\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-2025-25977/ (Markdown: https://insights.sbomify.com/CVE-2025-25977/index.md)","id":"CVE-2025-25977","markdown":"https://insights.sbomify.com/CVE-2025-25977/index.md","name":"CVE-2025-25977","record":{"aliases":["DEBIAN-CVE-2025-25977","GHSA-v2mw-5mch-w8c5","UBUNTU-CVE-2025-25977"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript SVG library","requires_auth":"none","summary":"An attacker can execute arbitrary code via the StyleElement constructor in the canvg JavaScript library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"canvg","vendor":"canvg"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"An issue in canvg v.4.0.2 allows an attacker to execute arbitrary code via the Constructor of the class StyleElement.","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":"canvg Prototype Pollution vulnerability","id":"CVE-2025-25977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2025"},"n_packages":4,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2025-25983"},"packages":[{"ecosystem":"npm","fixed":["3.0.11"],"introduced":["0"],"last_affected":[],"package":"canvg","purl":null,"source":"GHSA-v2mw-5mch-w8c5"},{"ecosystem":"npm","fixed":["3.0.11"],"introduced":["0"],"last_affected":[],"package":"canvg","purl":"pkg:npm/canvg","source":"GHSA-v2mw-5mch-w8c5"},{"ecosystem":"npm","fixed":["4.0.3"],"introduced":["4.0.0"],"last_affected":[],"package":"canvg","purl":null,"source":"GHSA-v2mw-5mch-w8c5"},{"ecosystem":"npm","fixed":["4.0.3"],"introduced":["4.0.0"],"last_affected":[],"package":"canvg","purl":"pkg:npm/canvg","source":"GHSA-v2mw-5mch-w8c5"}],"prev":{"headline":"Prototype Pollution Vulnerability in parse-git-config","id":"CVE-2025-25975"},"products":["n/a"],"published":"2025-03-10","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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-12","vendors":["n/a"]},"summary":"An attacker can execute arbitrary code via the StyleElement constructor in the canvg JavaScript library.","url":"https://insights.sbomify.com/CVE-2025-25977/"}
