Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-1337 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/mattermost/mattermost-server/v6 (Go): affected all versions; fixed in 6.4.2\n- github.com/mattermost/mattermost-server/v6 (Go): affected all versions; fixed in 6.4.2\n- github.com/mattermost/mattermost-server/v6 (Go): affected all versions; fixed in 6.4.2\n- mattermost (Bitnami): affected from 5.37.0; fixed in 5.37.9, 6.2.5, 6.3.5, 6.4.2\n- github.com/mattermost/mattermost-server (Go): affected all versions; no fix listed\n- github.com/mattermost/mattermost-server/v5 (Go): affected all versions; no fix listed\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-2022-1337/ (Markdown: https://insights.sbomify.com/CVE-2022-1337/index.md)","id":"CVE-2022-1337","markdown":"https://insights.sbomify.com/CVE-2022-1337/index.md","name":"CVE-2022-1337","record":{"aliases":["BIT-mattermost-2022-1337","GHSA-f37q-q7p2-ccfc","GO-2022-0595"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost collaboration platform","requires_auth":"low_privilege","summary":"An authenticated attacker can crash the Mattermost server by requesting links to very large image files, causing an out-of-memory condition.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_server","vendor":"mattermost"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The image proxy component in Mattermost version 6.4.1 and earlier allocates memory for multiple copies of a proxied image, which allows an authenticated attacker to crash the server via links to very large image files.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"OOM DoS in Mattermost image proxy","id":"CVE-2022-1337","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mattermost:mattermost_server","products":["mattermost:mattermost_server"],"type":"denial_of_service","year":"2022"},"n_packages":6,"n_references":1,"next":{"headline":"Easily Generate Rest API Url \u003c= 1.0.0 -
