Published:April 04, 2024
Updated:October 07, 2026
MesonLSP is an unofficial, unendorsed language server for meson written in C++. A vulnerability in versions prior to 4.1.4 allows overwriting arbitrary files if the attacker can make the victim either run the language server within a specific crafted project or "mesonlsp --full". Version 4.1.4 contains a patch for this issue. As a workaround, avoid running "mesonlsp --full" and set the language server option "others.neverDownloadAutomatically" to "true".
