## Affected

- GramSearch telegram-search: through 1.2.8

## Description

telegram-search contains a stored cross-site scripting vulnerability that allows remote attackers to execute arbitrary JavaScript in victims' browsers by sending crafted messages containing unsanitized HTML to a shared Telegram group. The highlightKeyword function in MessageList.vue passes raw message content directly to v-html without HTML escaping or sanitization, enabling stored, cross-user, zero-click execution of injected payloads such as image onerror handlers when victims browse or search messages.
