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-2026-18312 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-2026-18312/ (Markdown: https://insights.sbomify.com/CVE-2026-18312/index.md)","id":"CVE-2026-18312","markdown":"https://insights.sbomify.com/CVE-2026-18312/index.md","name":"CVE-2026-18312","record":{"aliases":["GHSA-fjx6-m8r4-w94f"],"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 inject malicious scripts via crafted metadata in Readwise Reader for Android, leading to stored XSS and potential data theft.","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 constructs URLs in its WebView using attacker-controlled metadata without proper encoding or escaping. The application interpolates untrusted values directly into URL strings and inserts them into the DOM via innerHTML. Because the interpolation occurs without HTML or JavaScript context encoding, a crafted metadata value can break out of the intended URL structure and inject script content. An attacker could supply a document containing malicious metadata that, once synchronized to an Android device and rendered in the Reader WebView, results in execution of injected script content, enabling stored cross-site scripting (XSS)","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"CVE-2026-18312","id":"CVE-2026-18312","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"rpcapd memory leak in libpcap before 1.10.7","id":"CVE-2026-18313"},"packages":[],"prev":{"headline":"CVE-2026-18311","id":"CVE-2026-18311"},"products":["Reader"],"published":"2026-09-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-25","vendors":["Readwise"]},"summary":"Attackers can inject malicious scripts via crafted metadata in Readwise Reader for Android, leading to stored XSS and potential data theft.","url":"https://insights.sbomify.com/CVE-2026-18312/"}
