SCA: security update for ep_etherpad-lite (GHSA-vqfp-p66c-xrp9)

medium Tenable Self-Hosted Container Security Plugin ID 445958

Description

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

 - Etherpad is a real-time collaborative editor. From 2.6.0 until 3.1.0, Etherpad's
 src/node/hooks/express/tokenTransfer.ts uses POST /tokenTransfer to store an author token for transfer
 between browsers and exposes it through GET /tokenTransfer/{uuid}. Although the record includes createdAt,
 the transfer has no expiration check, is not removed after successful redemption, and is returned by
 res.send(tokenData), including the raw author token. An unauthenticated attacker who obtains a transfer
 UUID can repeatedly redeem it, receive fresh author cookies, read the cleartext token, and impersonate the
 originating author for pad read and write operations. This issue is fixed in version 3.1.0.
 (CVE-2026-55088)

Solution

Update the ep_etherpad-lite library and its related packages to version 3.1.0 or later.
