SCA: security update for github.com/jasonlovesdoggo/abacus (GHSA-vh64-54px-qgf8)

high Tenable Self-Hosted Container Security Plugin ID 421015

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Abacus is a highly scalable and stateless counting API. A critical goroutine leak vulnerability has been
 identified in the Abacus server's Server-Sent Events (SSE) implementation. The issue occurs when clients
 disconnect from the /stream endpoint, as the server fails to properly clean up resources and terminate
 associated goroutines. This leads to resource exhaustion where the server continues running but eventually
 stops accepting new SSE connections while maintaining high memory usage. The vulnerability specifically
 involves improper channel cleanup in the event handling mechanism, causing goroutines to remain blocked
 indefinitely. This vulnerability is fixed in 1.4.0. (CVE-2025-27421)
