As a result the earliest affected version is actually 1.1.1 rather than 1.1.2 as was originally reported. A corrected report can be found below. Title: Read-only directory traversal in Etherpad Minify Reporter: Tom Hunkapiller Versions: 1.1.1 through 1.5.2 Description: Tom Hunkapiller reported a vulnerability in the minify feature of current Etherpad releases. Backslashes are replaced with slashes in the path parameter of HTTP API calls after path normalization is applied, allowing an attacker supplying specially-crafted requests to remotely read arbitrary files on the server's filesystem with the privileges of the account running the service. Notes: This bug was introduced in commit 7b518eeb which was initially included in the 1.1.1 release, and is fixed in commit 9d4e5f6 which appears in the 1.5.3 release.
