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-2026-18772 in the wild and no public exploit code.\n\nAffected product: Samsung Open Source rlottie. 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-2026-18772/ (Markdown: https://insights.sbomify.com/CVE-2026-18772/index.md)","id":"CVE-2026-18772","markdown":"https://insights.sbomify.com/CVE-2026-18772/index.md","name":"CVE-2026-18772","record":{"aliases":["DEBIAN-CVE-2026-18772","GHSA-9hrp-c4q8-hf75","UBUNTU-CVE-2026-18772"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"rlottie animation library","requires_auth":"none","summary":"Attackers can cause denial of service via exponential data expansion in the rlottie library due to improper memory allocation controls.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"samsung.tv_appliance","cpe":[{"product":"rlottie","vendor":"samsung"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1325","name":"Improperly Controlled Sequential Memory Allocation"}],"description":"Improperly controlled sequential memory allocation vulnerability in Samsung Open Source rlottie allows Exponential Data Expansion.","ecosystems":[],"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":"Denial of service in rlottie","id":"CVE-2026-18772","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"NousResearch hermes-agent Quick run.py _check_slash_access authorization","id":"CVE-2026-18773"},"packages":[],"prev":{"headline":"Missing Authentication for Critical Function in TMT Machine's Talassoft Industrial Management Software","id":"CVE-2026-18771"},"products":["rlottie"],"published":"2026-08-04","related":[{"cvss_score":6.5,"headline":"Denial of service in rlottie","id":"CVE-2026-19587","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":6.5,"headline":"Integer overflow in rlottie","id":"CVE-2026-19588","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":6.5,"headline":"Denial of service in rlottie","id":"CVE-2026-19517","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":6.5,"headline":"Integer overflow in rlottie","id":"CVE-2026-19518","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":5.5,"headline":"Integer overflow in rlottie","id":"CVE-2026-15551","kev_date_added":null,"published":"2026-07-13"},{"cvss_score":5.1,"headline":"Use after free in rLottie","id":"CVE-2025-0634","kev_date_added":null,"published":"2025-06-30"}],"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":"2026-08-12","vendors":["Samsung Open Source"]},"summary":"Attackers can cause denial of service via exponential data expansion in the rlottie library due to improper memory allocation controls.","url":"https://insights.sbomify.com/CVE-2026-18772/"}
