This affects the function hex_hash_to_int16 of the file lmcache/integration/vllm/utils.py of the component KV Cache Handler. Executing a manipulation can lead to use of weak hash. The attack needs to be launched locally. The attack requires a high level of complexity. It is indicated that the exploitability is difficult. The exploit has been published and may be used. Upgrading to version 0.5.5 is able to mitigate this issue. This patch is called ce08eea76ce5898200efee55f4932fd07a7cabeb. It is suggested to upgrade the affected component. A contributor of the project confirms: \"hex_hash_to_int16() was introduced in 0.3.1 (PR #882, commit f5174701). It is not present in 0.3.0, and it is still present in 0.4.7 through 0.5.4.\"","state":0,"publishedAt":"2026-06-04T14:45:10.552+00:00","modifiedAt":"2026-10-17T06:18:40.529+00:00","affected":[{"ecosystem":"Vendor product","name":"LMCache","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"LMCache\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.5.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.5\",\n                            \"status\": \"unaffected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:lmcache:lmcache:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"KV Cache Handler\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","score":2,"severity":"LOW"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L/E:P/RL:O/RC:C","score":3.6,"severity":"LOW"},{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L/E:P/RL:O/RC:C","score":3.6,"severity":"LOW"},{"system":"CVSS 2.0","vector":"AV:L/AC:H/Au:S/C:N/I:P/A:P/E:POC/RL:OF/RC:C","score":2.4,"severity":null}],"references":["https://vuldb.com/vuln/368261","https://vuldb.com/vuln/368261/cti","https://vuldb.com/cve/CVE-2026-10813","https://vuldb.com/submit/831641","https://github.com/LMCache/LMCache/issues/3301","https://github.com/LMCache/LMCache/pull/4783","https://github.com/LMCache/LMCache/commit/ce08eea76ce5898200efee55f4932fd07a7cabeb","https://pypi.org/project/lmcache/0.5.5/","https://github.com/LMCache/LMCache/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-10813","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-10813","identifiers":["CVE-2026-10813"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
