https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42790 --- Comment #27 from Martin Renvoize (ashimema) <martin.renvoize@openfifth.co.uk> --- Created attachment 205491 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=205491&action=edit Bug 42790: (QA follow-up) Escape error messages in the extend booking modal showError() interpolated its message argument directly into innerHTML. One call site passes result.error, API response text, through unescaped, making this a stored/reflected XSS vector if the API ever echoes attacker-influenced content in an error message. Build the alert with textContent instead of a template literal.
