In affected versions some avo fields are vulnerable to Cross Site Scripting (XSS) when rendering html based content. Attackers do need form edit privilege in order to successfully exploit this vulnerability, but the results are stored and no specific timing is required. This issue has been addressed in commit `7891c01e` which is expected to be included in the next release of avo. Users are advised to configure CSP headers for their application and to limit untrusted user access as a mitigation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/avo-hq/avo/commit/7891c01e1fba9ca5d7dbccc43d27f385e5d08563","https://github.com/avo-hq/avo/security/advisories/GHSA-5cr9-5jx3-2g39","https://github.com/avo-hq/avo/commit/7891c01e1fba9ca5d7dbccc43d27f385e5d08563","https://github.com/avo-hq/avo/security/advisories/GHSA-5cr9-5jx3-2g39"],"products":["avohq:avo"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-34103","score":0.00563,"percentile":0.46838,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5cr9-5jx3-2g39","url":"https://osv.dev/vulnerability/GHSA-5cr9-5jx3-2g39","summary":"avo vulnerable to Stored XSS (Cross Site Scripting) in html content based fields","modified":"2026-09-10T03:50:02.444566381Z","packages":[{"ecosystem":"RubyGems","name":"avo","purl":"pkg:gem/avo","ranges":["<2.33.3"],"fixed":["2.33.3"]},{"ecosystem":"RubyGems","name":"avo","purl":"pkg:gem/avo","ranges":[">=3.0.0.pre1 <=3.0.0.pre12"],"fixed":[]}]}],"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).
