It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-23512 and fix it if it is affected.\n\nWhat it is: CVE-2026-23512 is a high-severity vulnerability in sumatrapdfreader sumatrapdf, published on 14 Jan 2026. It can only be exploited from the same machine or local network, 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-2026-23512 exists.\n\nAffected product: sumatrapdfreader sumatrapdf. 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-2026-23512/ (Markdown: https://insights.sbomify.com/CVE-2026-23512/index.md)","id":"CVE-2026-23512","markdown":"https://insights.sbomify.com/CVE-2026-23512/index.md","name":"CVE-2026-23512","record":{"aliases":["GHSA-rqg5-gj63-x4mv"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"PDF reader","requires_auth":"none","summary":"Attackers can execute arbitrary code by placing a malicious notepad.exe in the installation directory when Advanced Options are used.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"sumatrapdf","vendor":"sumatrapdfreader"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-426","name":"Untrusted Search Path"}],"description":"SumatraPDF is a multi-format reader for Windows.
