Summary
CVE-2022-34094 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Softwarepublico I3Geo. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 16.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-34094 is a reflected cross-site scripting vulnerability (CWE-79) affecting version 7.0.5 of i3geo, the mapping component of the Brazilian Public Software Portal. The flaw resides in request_token.php and permits injection of unfiltered script content into responses returned to the browser.
An unauthenticated remote attacker can supply a crafted request that causes the application to echo attacker-controlled JavaScript back to a victim who follows a malicious link. Because the CVSS vector shows no authentication requirement, low attack complexity, and changed scope, successful exploitation can read or modify data within the victim’s session context, including actions performed on behalf of an authenticated user.
The EPSS score rose from a low baseline to a peak of 0.1135 on 2025-12-11 before receding to the current value of 0.0191, indicating a measurable increase in observed exploitation interest after public disclosure. Public references consist of issue reports and a proof-of-concept but contain no vendor-supplied patches or mitigation guidance.
