CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-29858 is a high-severity PHP Remote File Inclusion (CWE-98) vulnerability in Aapanel Aapanel. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-29858 affects aaPanel version 7.57.0, where a lack of path validation enables local file inclusion (LFI) attacks, leading to sensitive information exposure. Published on 2026-03-18, this vulnerability is classified under CWE-98 and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with no effects on integrity or availability.
Remote attackers require no privileges, authentication, or user interaction to exploit this issue over the network with low complexity. Successful exploitation allows reading arbitrary local files on the affected server, potentially exposing configuration data, credentials, or other sensitive content.
Mitigation details and further analysis are available in referenced sources, including the official aaPanel GitHub repository at https://github.com/aapanel/aapanel and vulnerability research at https://github.com/mbiesiad/vulnerability-research/tree/main/CVE-2026-29858.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and static analysis can discover missing filename restrictions before deployment.
Validating all inputs before they reach include/require statements directly stops untrusted filenames from being used.
Enforcing access authorizations on resources limits what an included file can reach even if a bad name is supplied.
Information-flow rules can block the loading of external or unauthorized files into the PHP process.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices such as input validation and allow-listing of include paths directly prevent the weakness.
Hardened runtime configuration (e.g., allow_url_include=off) directly blocks RFI even if code is flawed.
Execution restrictions can prevent the remote payload from running, while eliminating the weakness reduces the need for such controls.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect RFI but does not prevent the weakness by itself.
Secure development lifecycle mandates input validation and safe include/require patterns that directly prevent remote file inclusion.
Application security requirements explicitly call for controls against injection and unsafe file operations.
Secure architecture principles reduce attack surface but do not specifically address dynamic file inclusion.
Secure coding standards directly require whitelisting and sanitization of filenames used in include/require statements.
