In versions 10.25.7 and below, the date filter's strftime implementation parses width specifiers like %9999999d and forwards the captured width unchecked into pad()/padStart(), leading to memory and render limit bypass. In src/util/underscore.ts, the pad loop performs unbounded string concatenation without consulting the Context's memoryLimit or renderLimit, so a single small template ({{ x | date: '%5000000d' }}) produces megabytes of output and unbounded CPU. The memoryLimit and renderLimit options the docs (src/liquid-options.ts:87-92) advertise as DoS controls — and which the docstring explicitly mentions for strftime — are entirely bypassed. Exploitation can cause large memory allocations, high CPU usage, or OOM crashes per render. This issue has been fixed in version 10.26.0.","state":0,"publishedAt":"2026-06-17T22:32:20.643+00:00","modifiedAt":"2026-06-18T12:49:15.361+00:00","affected":[{"ecosystem":"Vendor product","name":"liquidjs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"harttle\",\n                    \"product\": \"liquidjs\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 10.26.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/harttle/liquidjs/security/advisories/GHSA-hh27-hf48-9f5q","https://github.com/harttle/liquidjs/commit/3129d46dc95efa357b00e5a57ee1af80a13d72ed","https://github.com/harttle/liquidjs/releases/tag/v10.26.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-45357","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-45357","identifiers":["CVE-2026-45357"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
