An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2006-1993 exists.\n\nAffected product: Mozilla Firefox. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2006-1993/ (Markdown: https://insights.sbomify.com/CVE-2006-1993/index.md)","id":"CVE-2006-1993","markdown":"https://insights.sbomify.com/CVE-2006-1993/index.md","name":"CVE-2006-1993","record":{"aliases":["DSA-1053-1","DSA-1055-1","GHSA-gh5c-2j93-h8q7"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute arbitrary code in Firefox via crafted JavaScript exploiting a use-after-free in designMode.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"firefox","vendor":"mozilla"}],"cvss":{"score":5.1,"severity":"medium","source":"nvd","vector":"AV:N/AC:H/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Mozilla Firefox 1.5.0.2, when designMode is enabled, allows remote attackers to cause a denial of service and possibly execute arbitrary code via certain Javascript that is not properly handled by the contentWindow.focus method in an iframe, which causes a reference to a deleted controller context object.
