An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-18311 in the wild and no public exploit code.\n\nAffected product: Readwise Reader. 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-2026-18311/ (Markdown: https://insights.sbomify.com/CVE-2026-18311/index.md)","id":"CVE-2026-18311","markdown":"https://insights.sbomify.com/CVE-2026-18311/index.md","name":"CVE-2026-18311","record":{"aliases":["GHSA-p2jj-7m4x-3gfh"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Readwise Reader Android","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in the Readwise Reader Android app via stored XSS in imported document metadata, potentially compromising synced devices.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Readwise Reader for Android contains a cross-site scripting vulnerability due to missing HTML sanitization in its processing of imported document metadata.
