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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

Upgrade to version 0.27.5 or later, where this path traversal vulnerability is fixed. Since this is an application-level vulnerability, patching the software is the recommended and effective mitigation. No other vendor advisory or temporary fixes are indicated.

Description

CVE-2026-33528 is a path traversal vulnerability in yusing godoxy versions prior to 0.27.5. The vulnerability exists in the file content API endpoint at /api/v1/file/content, where the filename parameter is not properly sanitized. An authenticated attacker can exploit this to read or write files outside the intended config directory, potentially accessing sensitive files such as TLS private keys and OAuth tokens. The issue is fixed in version 0.27.5.

Impact

An authenticated attacker with high privileges can exploit this vulnerability to read or write arbitrary files accessible to the container's user ID. This includes sensitive configuration files such as TLS private keys and OAuth refresh tokens, potentially leading to credential compromise and further system access. There is no direct impact on availability.

Summary

GoDoxy is a reverse proxy and container orchestrator. In versions before 0.27.5, the /api/v1/file/content endpoint accepts a filename query parameter that is concatenated with a relative base path ('config') using path.Join without proper sanitization. This allows an authenticated user to use '../' sequences to traverse directories and access or modify files outside the intended directory. The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). The CVSS 3.1 score is 6.5 (medium severity) with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N, indicating network attack vector, low complexity, high privileges required, no user interaction, unchanged scope, and high confidentiality and integrity impact but no availability impact. Version 0.27.5 addresses this issue.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
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…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
