Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Until an official patch is released, organizations should implement the following mitigations: 1) Restrict access to the aaPanel management interface by IP whitelisting or VPN-only access to reduce exposure to untrusted networks. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious file inclusion patterns or path traversal attempts targeting aaPanel endpoints. 3) Conduct thorough auditing and monitoring of server logs to identify anomalous requests indicative of LFI exploitation attempts. 4) Harden server file permissions to limit the readability of sensitive files by the web server process, minimizing the impact of successful LFI exploitation. 5) Consider temporarily disabling or isolating vulnerable aaPanel instances in high-risk environments until patches are available. 6) Stay updated with vendor advisories and apply patches promptly once released. 7) Educate system administrators about the vulnerability and encourage proactive incident response planning.

Description

CVE-2026-29858 is a high-severity Local File Inclusion (LFI) vulnerability in aaPanel version 7.57.0 caused by insufficient path validation. This flaw allows unauthenticated remote attackers to include local files on the server, potentially exposing sensitive information. The vulnerability does not require user interaction or privileges and can be exploited over the network. While no known exploits are currently active in the wild, the vulnerability poses a significant risk due to its ease of exploitation and impact on confidentiality. No patches have been published yet, increasing the urgency for mitigation. Organizations using aaPanel, especially web hosting providers and enterprises relying on this control panel, should prioritize risk assessment and implement immediate protective measures. Countries with widespread aaPanel usage and significant web hosting infrastructure are at higher risk. Given the CVSS score of 7.

Impact

The primary impact of this vulnerability is the unauthorized disclosure of sensitive information stored on the affected server. Attackers can access configuration files, credentials, or other sensitive data that could facilitate further attacks such as privilege escalation, lateral movement, or data breaches. Since aaPanel is widely used in web hosting environments, exploitation could compromise multiple hosted websites or services, leading to reputational damage, regulatory penalties, and financial loss. The vulnerability does not directly affect system integrity or availability but significantly undermines confidentiality. Organizations relying on aaPanel for server management, especially those hosting sensitive or regulated data, face increased risk. The lack of authentication requirement and ease of exploitation broaden the potential attack surface, making automated scanning and mass exploitation plausible once public exploits emerge.

Summary

CVE-2026-29858 is a Local File Inclusion (LFI) vulnerability identified in aaPanel version 7.57.0, a popular web hosting control panel. The root cause is a lack of proper path validation when handling file inclusion requests, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). This flaw allows an attacker to craft a specially designed request that tricks the application into including arbitrary local files. Since the vulnerability is remotely exploitable without authentication or user interaction, an attacker can leverage it to read sensitive files such as configuration files, password stores, or other critical data residing on the server. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, and high confidentiality impact with no integrity or availability impact. Although no public exploits or patches are currently available, the vulnerability's nature and impact make it a critical concern for organizations using aaPanel. The absence of patch links suggests that vendors or maintainers have yet to release a fix, emphasizing the need for immediate mitigation strategies.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
