Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-27592 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- miniflux.app/v2 (Go): affected from 2.0.25; fixed in 2.0.43\n- miniflux.app/v2 (Go): affected from 2.0.25; fixed in 2.0.43\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-2023-27592/ (Markdown: https://insights.sbomify.com/CVE-2023-27592/index.md)","id":"CVE-2023-27592","markdown":"https://insights.sbomify.com/CVE-2023-27592/index.md","name":"CVE-2023-27592","record":{"aliases":["GHSA-mqqg-xjhj-wfgw"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Miniflux feed reader","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary JavaScript in a victim's browser via crafted RSS feeds, potentially leading to account takeover or admin access.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"miniflux","vendor":"miniflux_project"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Miniflux is a feed reader. Since v2.0.25, Miniflux will automatically proxy images served over HTTP to prevent mixed content errors. \n\nWhen an outbound request made by the Go HTTP client fails, the `html.ServerError` is returned unescaped without the expected Content Security Policy header added to valid responses.\n\nBy creating an RSS feed item with the inline description containing an `\u003cimg\u003e` tag with a `srcset` attribute pointing to an invalid URL like `http:a\u003cscript\u003ealert(1)\u003c/script\u003e`, we can coerce the proxy handler into an error condition where the invalid URL is returned unescaped and in full.\n\nThis results in JavaScript execution on the Miniflux instance as soon as the user is convinced (e.g. by a message in the alt text) to open the broken image.\n\nAn attacker can execute arbitrary JavaScript in the context of a victim Miniflux user when they open a broken image in a crafted RSS feed. This can be used to perform actions on the Miniflux instance as that user and gain administrative access to the Miniflux instance if it is reachable and the victim is an administrator.\n\nA patch is available in version 2.0.43.
