CVE-2020-29007 is a critical remote code execution vulnerability in the MediaWiki Score extension (through version 0.3.0) that stems from improper sandboxing of the GNU LilyPond executable. This flaw allows any user with article editing privileges, including potentially unauthenticated anonymous users, to execute arbitrary Scheme or shell code by embedding malicious code within crafted image data used for musical scores. With a CVSS score of 9.8 (CRITICAL), this vulnerability is easily exploitable over the network with no user interaction, leading to complete compromise of confidentiality, integrity, and availability. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed on the CISA KEV catalog, indicating no active exploitation observed. Community discussion and media coverage are also minimal.
