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-2026-26833 exists.\n\nAffected packages and fixed versions:\n- thumbler (npm): affected all versions up to 1.1.2; no fix listed\n- thumbler (npm): affected all versions up to 1.1.2; 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-2026-26833/ (Markdown: https://insights.sbomify.com/CVE-2026-26833/index.md)","id":"CVE-2026-26833","markdown":"https://insights.sbomify.com/CVE-2026-26833/index.md","name":"CVE-2026-26833","record":{"aliases":["GHSA-mvhf-547c-h55r"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js image library","requires_auth":"none","summary":"An attacker can execute arbitrary OS commands by injecting malicious input into the thumbnail function parameters in the thumbler library.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"thumbler","vendor":"mmahrous"}],"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-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"thumbler through 1.1.2 allows OS command injection via the input, output, time, or size parameter in the thumbnail() function because user input is concatenated into a shell command string passed to child_process.exec() without proper sanitization or escaping.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":"2026-03-24","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-03-24T16:15:38Z","kind":"github_poc","ref":"https://github.com/zebbernCVE/CVE-2026-26833","stars":0,"title":"Advisory for thumbler"}],"tier":"weaponised"},"has_fix":false,"headline":"thumbler allows OS Command Injection","id":"CVE-2026-26833","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":2,"n_references":4,"next":{"headline":"Memory corruption in n/a","id":"CVE-2026-26846"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.1.2"],"package":"thumbler","purl":null,"source":"GHSA-mvhf-547c-h55r"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.1.2"],"package":"thumbler","purl":"pkg:npm/thumbler","source":"GHSA-mvhf-547c-h55r"}],"prev":{"headline":"node-tesseract-ocr is vulnerable to OS Command Injection through unsanitized recognize() function parameter","id":"CVE-2026-26832"},"products":["n/a"],"published":"2026-03-25","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-28","vendors":["n/a"]},"summary":"An attacker can execute arbitrary OS commands by injecting malicious input into the thumbnail function parameters in the thumbler library.","url":"https://insights.sbomify.com/CVE-2026-26833/"}
