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: There is no known exploitation of CVE-2026-57848 in the wild and no public exploit code.\n\nAffected product: stoatchat Stoat for Android. 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-2026-57848/ (Markdown: https://insights.sbomify.com/CVE-2026-57848/index.md)","id":"CVE-2026-57848","markdown":"https://insights.sbomify.com/CVE-2026-57848/index.md","name":"CVE-2026-57848","record":{"aliases":["GHSA-cr46-r787-v566"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Android chat application","requires_auth":"none","summary":"Attackers can exploit an exported activity to leak internal app files, including databases and auth tokens, leading to data disclosure and account takeover.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-926","name":"Improper Export of Android Application Components"}],"description":"Stoat for Android exports the chat.stoat.activities.ShareTargetActivity component (reachable to any process on the device via the android.intent.action.SEND intent) and accepts the file to share as a URI supplied through the android.intent.extra.STREAM extra. The activity does not validate or filter the incoming URI before using it as the outgoing attachment, so a caller can pass a file:// URI pointing at the application's own internal storage (for example /data/data/chat.revolt/databases/revolt.db, cached authentication token files, or preferences) and have the app treat that internal file as a user-selected attachment. An attacker who can invoke intents on the victim's device (via ADB access, a co-installed malicious application, or any other route that reaches Android's intent dispatch) can launch ShareTargetActivity with such a URI and cause the victim, on a single channel-selection interaction, to send the internal file to any Stoat channel or user of the attacker's choosing. The composer displays the attachment as \\\"attachment\\\" with no filename indication, so the victim has no visible signal that the file being sent is their own internal application data. Consequences include disclosure of the local Stoat database (message history, contact list, cached content), disclosure of authentication tokens permitting full account takeover, and disclosure of any other file readable by the app process.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Stoat for Android Internal File Disclosure via Exported ShareTargetActivity URI Validation","id":"CVE-2026-57848","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-57849"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-57847"},"products":["Stoat for Android"],"published":"2026-07-18","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":"2026-07-20","vendors":["stoatchat"]},"summary":"Attackers can exploit an exported activity to leak internal app files, including databases and auth tokens, leading to data disclosure and account takeover.","url":"https://insights.sbomify.com/CVE-2026-57848/"}
