Out-of-bounds heap write in the RAR5 recovery-volume (.rev) parser of WinRAR, RAR, UnRAR, and unrar.dll (versions before 7.23) lets an attacker corrupt heap memory when a victim runs a recovery, test, or repair operation on a crafted multi-file .rev set. Because subsequent .rev files supply a RecNum value validated only against their own TotalCount and never against the actual RecItems allocation, an attacker-controlled 32-bit value can be written far past the buffer, enabling memory corruption and potential code execution. There is no public exploit identified at time of analysis, but this is the RAR5-path sibling of the previously exploited CVE-2023-40477, and CWE-787 flaws in WinRAR have historically led to reliable RCE.
Path traversal in Rarlab RAR App for Android up to 7.11 Build 127 allows remote attackers to read or write arbitrary files by convincing a user to open a malicious RAR archive. Exploitation is highly complex and requires user interaction. Public proof-of-concept code is available, but the EPSS score of 0.33% indicates a low probability of widespread exploitation; the vendor has fixed the issue in version
Directory Traversal exists in RAR 4.x and 5.x because an unpack operation follows any symlinks, including symlinks contained in the archive. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
