Any signed-in user can exploit it over the 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-2026-7501 exists.\n\nAffected product: LinkStackOrg LinkStack. 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-2026-7501/ (Markdown: https://insights.sbomify.com/CVE-2026-7501/index.md)","id":"CVE-2026-7501","markdown":"https://insights.sbomify.com/CVE-2026-7501/index.md","name":"CVE-2026-7501","record":{"aliases":["GHSA-3v6f-p2hc-xq2j"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"LinkStack web application","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts via the pageDescription field in LinkStack, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A weakness has been identified in LinkStackOrg LinkStack up to 4.8.6.
