Arbitrary file upload in PerfreeBlog 4.0.11 lets an authenticated user abuse the installPlugin function to upload malicious files, likely enabling web shell deployment and remote code execution on the blog server. A public technical write-up with proof-of-concept exists on GitHub, though the flaw is not listed in CISA KEV and carries a low EPSS score (0.28%, 20th percentile), indicating no confirmed widespread exploitation yet.
Arbitrary file upload in PerfreeBlog v4.0.11 lets an authenticated attacker abuse the installTheme function to upload malicious files (e.g. a web shell), typically resulting in server-side code execution and full compromise of the blog host. The flaw is a classic unrestricted-upload issue (CWE-434) reachable over the network by a low-privileged authenticated user; publicly available exploit code exists in the form of a GitHub write-up, though EPSS exploitation probability remains low (0.28%, 20th percentile) and it is not listed in CISA KEV.
Arbitrary file deletion in PerfreeBlog 4.0.11 lets attackers remove files outside the intended theme directory by abusing the unInstallTheme theme-management function. Publicly available exploit code exists, though the flaw is not on CISA KEV and carries a low EPSS score (0.31%, 22nd percentile), indicating limited real-world exploitation to date. The CVSS 3.1 vector (PR:N/UI:R) implies an unauthenticated attacker who tricks an interacting user into triggering the deletion, consistent with a CSRF-style delivery against an administrator.
Arbitrary file read in PerfreeBlog v4.0.11 allows unauthenticated remote attackers to read files outside the intended web root by bypassing path validation in the validThemeFilePath function. The vulnerability is network-exploitable with no authentication or user interaction required, and a public proof-of-concept is documented on GitHub. No active exploitation has been confirmed by CISA KEV, and the EPSS score of 0.33% suggests limited observed exploitation activity despite the POC's existence.
