Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-5522 in the wild and no public exploit code.\n\nAffected product: Mattermost Mattermost. 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-2023-5522/ (Markdown: https://insights.sbomify.com/CVE-2023-5522/index.md)","id":"CVE-2023-5522","markdown":"https://insights.sbomify.com/CVE-2023-5522/index.md","name":"CVE-2023-5522","record":{"aliases":["GHSA-2w9p-mj8f-374x"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost mobile app","requires_auth":"low_privilege","summary":"An attacker can freeze the Mattermost mobile app by sending posts with excessive emojis, causing a denial of service for users viewing the channel.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost","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-400","name":"Uncontrolled Resource Consumption"}],"description":"Mattermost Mobile fails to limit the maximum number of Markdown elements in a post allowing an attacker to send a post with hundreds of emojis to a channel and freeze the mobile app of users when viewing that particular channel.","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":"Mobile app freezes when receiving a post with hundreds of emojis","id":"CVE-2023-5522","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mattermost:mattermost","products":["mattermost:mattermost"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"M-Files Web Companion allows Remote Code Execution","id":"CVE-2023-5523"},"packages":[],"prev":{"headline":"Incorrect Authorization in tiann/kernelsu","id":"CVE-2023-5521"},"products":["Mattermost"],"published":"2023-10-17","related":[{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2019-20851","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":8.7,"headline":"Malicious remote can add users to arbitrary teams and channels","id":"CVE-2024-39274","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":8.7,"headline":"Malicious remote can invite itself to an arbitrary local channel","id":"CVE-2024-39777","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":8.1,"headline":"Timing attack during remote cluster token comparison when shared channels are enabled","id":"CVE-2024-39830","kev_date_added":null,"published":"2024-07-03"},{"cvss_score":8.1,"headline":"Lack of server certificate validation in websockets connection","id":"CVE-2023-3615","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-13891","kev_date_added":null,"published":"2020-06-26"},{"cvss_score":7.4,"headline":"Existing local user overwritten by malicious remote","id":"CVE-2024-36492","kev_date_added":null,"published":"2024-08-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2024-09-05","vendors":["Mattermost"]},"summary":"An attacker can freeze the Mattermost mobile app by sending posts with excessive emojis, causing a denial of service for users viewing the channel.","url":"https://insights.sbomify.com/CVE-2023-5522/"}
