{"cve":"CVE-2023-27476","nvd":{"published":"2023-03-08T00:15:08.997","modified":"2026-06-17T05:45:17.327","status":"Modified","description":"OWSLib is a Python package for client programming with Open Geospatial Consortium (OGC) web service interface standards, and their related content models. OWSLib's XML parser (which supports both `lxml` and `xml.etree`) does not disable entity resolution, and could lead to arbitrary file reads from an attacker-controlled XML payload. This affects all XML parsing in the codebase. This issue has been addressed in version 0.28.1. All users are advised to upgrade. The only known workaround is to patch the library manually. See `GHSA-8h9c-r582-mggc` for details.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-611"],"references":["https://github.com/geopython/OWSLib/pull/863/commits/b92687702be9576c0681bb11cad21eb631b9122f","https://github.com/geopython/OWSLib/security/advisories/GHSA-8h9c-r582-mggc","https://lists.debian.org/debian-lts-announce/2023/06/msg00032.html","https://securitylab.github.com/advisories/GHSL-2022-131_owslib/","https://www.debian.org/security/2023/dsa-5426"],"products":["osgeo:owslib"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-27476","score":0.00977,"percentile":0.62158,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-8h9c-r582-mggc","url":"https://osv.dev/vulnerability/GHSA-8h9c-r582-mggc","summary":"OWSLib vulnerable to XML External Entity (XXE) Injection","modified":"2026-02-22T22:56:04.328193Z","packages":[{"ecosystem":"PyPI","name":"owslib","purl":"pkg:pypi/owslib","ranges":["<0.28.1"],"fixed":["0.28.1"]}]},{"id":"PYSEC-2023-86","url":"https://osv.dev/vulnerability/PYSEC-2023-86","summary":"","modified":"2026-02-22T22:49:14.935552Z","packages":[{"ecosystem":"PyPI","name":"owslib","purl":"pkg:pypi/owslib","ranges":["<0.28.1"],"fixed":["0.28.1"]}]}],"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).
