SCA: security update for parse-server (GHSA-827p-g5x5-h86c)

high Tenable Self-Hosted Container Security Plugin ID 438917

Description

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

 - Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js.
 Prior to 9.6.0-alpha.19 and 8.6.43, a remote attacker can crash the Parse Server by subscribing to a
 LiveQuery with an invalid regular expression pattern. The server process terminates when the invalid
 pattern reaches the regex engine during subscription matching, causing denial of service for all connected
 clients. The fix in 9.6.0-alpha.19 and 8.6.43 validates regular expression patterns at subscription time,
 rejecting invalid patterns before they are stored. Additionally, a defense-in-depth try-catch prevents any
 subscription matching error from crashing the server process. As a workaround, disable LiveQuery if it is
 not needed. (CVE-2026-32770)

Solution

Update the parse-server library and its related packages to version 8.6.43 or later.
