CVE-2026-34455 identifies a critical SQL injection vulnerability in Hi.Events, an open-source event management and ticket selling platform, affecting versions 0.8.0-beta.1 through 1.7.0-beta. This flaw arises from the direct use of user-supplied 'sort_by' query parameters in Eloquent's orderBy() function without proper validation, enabling attackers to execute arbitrary SQL commands. Rated with a CVSSv4 score of 8.7 (High), this vulnerability allows unauthenticated, remote attackers to achieve high confidentiality impact with low attack complexity, further exacerbated by PostgreSQL's support for stacked queries. While no public exploit code is currently available and it is not listed in CISA's KEV catalog, the CVE is on the "Hot List," indicating active monitoring or elevated concern. Organizations using affected versions should upgrade to 1.7.1-beta or later immediately to remediate this risk.
