It was discovered that the XML::Atom Perl module before version 0.39 did not disable external entities when parsing XML from potentially untrusted sources. This may allow attackers to gain read access to otherwise protected resources, depending on how the library is used.

An issue was discovered in the atom crate before 0.3.6 for Rust. An unsafe Send implementation allows a cross-thread data race.

atom-node-module-installer installs node modules for atom-shell applications. atom-node-module-installer binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.
