{"cve":"CVE-2026-44844","nvd":{"published":"2026-05-26T21:16:39.163","modified":"2026-07-24T11:10:00.170","status":"Deferred","description":"eml_parser serves as a python module for parsing eml files and returning various information found in the e-mail as well as computed information. Prior to 3.0.1, EmlParser.get_raw_body_text() recurses unconditionally for every nested message/rfc822 attachment without any depth limit. An attacker who can supply a badly crafted EML file with approximately 120 nested message/rfc822 parts triggers an unhandled RecursionError and aborts parsing of the message. A 12 KB EML file is enough to crash a worker. Though this causes the parser to crash, it is an unlikely scenario as the suggested EML that crashes the parser would not pass basic RFC compliance tests. This vulnerability is fixed in 3.0.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":null,"cwes":["CWE-674"],"references":["https://github.com/GOVCERT-LU/eml_parser/security/advisories/GHSA-g47v-rwmh-r9f8","https://github.com/GOVCERT-LU/eml_parser/security/advisories/GHSA-g47v-rwmh-r9f8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-44844","score":0.00396,"percentile":0.33811,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-g47v-rwmh-r9f8","url":"https://osv.dev/vulnerability/GHSA-g47v-rwmh-r9f8","summary":"eml_parser has recursion DoS via nested message/rfc822 attachments","modified":"2026-07-13T16:43:13.644927040Z","packages":[{"ecosystem":"PyPI","name":"eml-parser","purl":"pkg:pypi/eml-parser","ranges":["<3.0.1"],"fixed":["3.0.1"]}]},{"id":"PYSEC-2026-2468","url":"https://osv.dev/vulnerability/PYSEC-2026-2468","summary":"eml_parser has recursion DoS via nested message/rfc822 attachments","modified":"2026-07-13T16:31:45.571578729Z","packages":[{"ecosystem":"PyPI","name":"eml-parser","purl":"pkg:pypi/eml-parser","ranges":["<3.0.1"],"fixed":["3.0.1"]}]}],"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).
