Deeper analysis
CVE-2026-5577 is a SQL injection vulnerability in the Song-Li cross_browser project up to commit ca690f0fe6954fd9bcda36d071b68ed8682a786a. The issue resides in an unknown part of the file flask/uniquemachine_app.py within the details Endpoint component, where manipulation of the argument ID enables the injection. Associated with CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).
The vulnerability is exploitable remotely by unauthenticated attackers with network access and low complexity requirements. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption via crafted SQL payloads targeting the ID argument.
Advisories from VulDB (vuln/355347) and a public GitHub issue (wing3e/public_exp/issues/24) detail the flaw, noting that an exploit has been disclosed publicly and may be in use. The product follows a rolling release model, providing no specific version information for affected or patched releases. The vendor was notified early but has not responded or issued mitigations.
