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-2025-5455 in the wild and no public exploit code.\n\nAffected product: Qt. 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-2025-5455/ (Markdown: https://insights.sbomify.com/CVE-2025-5455/index.md)","id":"CVE-2025-5455","markdown":"https://insights.sbomify.com/CVE-2025-5455/index.md","name":"CVE-2025-5455","record":{"aliases":["ALSA-2025:9462","ALSA-2025:9486","AZL-64349","AZL-64361","DEBIAN-CVE-2025-5455","ECHO-a29a-8133-4b8d","GHSA-5cfg-qhv9-4842","MGASA-2025-0212","OESA-2025-1654","OESA-2025-1655","OESA-2025-1725","OESA-2025-1757","OESA-2025-2545","RHSA-2025:11841","RHSA-2025:9462","RHSA-2025:9486","RLSA-2025:9462","RLSA-2025:9486","UBUNTU-CVE-2025-5455","openSUSE-SU-2025:15240-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Qt framework","requires_auth":"none","summary":"Attackers can cause a denial of service by passing malformed URLs to Qt's qDecodeDataUrl function when assertions are enabled.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TQtC","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H/R:U/RE:M/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An issue was found in the private API function qDecodeDataUrl() in QtCore, which is used in QTextDocument and QNetworkReply, and, potentially, in user code.\n\nIf the function was called with malformed data, for example, an URL that\ncontained a \"charset\" parameter that lacked a value (such as\n\"data:charset,\"), and Qt was built with assertions enabled, then it would hit an assertion, resulting in a denial of service\n(abort).\n\nThis impacts Qt up to 5.15.18, 6.0.0-\u003e6.5.8, 6.6.0-\u003e6.8.3 and 6.9.0.
