Perl's read grows the buffer to the requested length before reading, so the declared Content-Length determines the allocation.\n\nAn attacker can trigger this through any route whose dispatch specification has a % body-parameter match, such as sub (POST + %name=), sending a Content-Length far larger than the body actually sent. No authentication is involved.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-789"],"references":["https://github.com/p5sagit/Web-Simple/commit/7e02c4f6204a2898938d357e6efe6dc2679af695.patch","https://metacpan.org/release/ETHER/Web-Simple-0.035/changes","http://www.openwall.com/lists/oss-security/2026/10/24/4"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-114629","score":0.00267,"percentile":0.18641,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
