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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.

Detectable: evidence found.
nuclei template: Bazarr < 1.4.3 - Arbitrary File Read
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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

Immediately restrict access to the /api/swaggerui/static endpoint using network-level controls such as firewalls or web application firewalls (WAFs) to limit exposure to trusted IPs or internal networks only.
Implement strict input validation and sanitization on file path parameters to prevent directory traversal sequences (e.g., ../) from being processed.
Monitor server logs and network traffic for unusual access patterns targeting the vulnerable endpoint or attempts to access sensitive files.
If possible, disable or remove the Swagger UI static component temporarily until a patch or official fix is available.
Keep Bazaar installations updated and subscribe to vendor advisories for patches addressing this vulnerability.
Employ intrusion detection/prevention systems (IDS/IPS) with signatures for directory traversal attacks to detect and block exploitation attempts.
Conduct internal audits to identify any unauthorized access or data exfiltration that may have occurred prior to mitigation.
Educate development and operations teams about secure coding practices to prevent similar vulnerabilities in custom components or integrations.

Description

An issue in the component /api/swaggerui/static of Bazaar v1.4.3 allows unauthenticated attackers to execute a directory traversal.

Impact

The primary impact of CVE-2024-40348 is unauthorized disclosure of sensitive information due to directory traversal, which can lead to data breaches, exposure of credentials, configuration files, or other critical assets. This can facilitate further attacks such as privilege escalation, lateral movement, or targeted exploitation of other vulnerabilities. Organizations relying on Bazaar v1.4.3 for version control or API documentation services may face increased risk of intellectual property theft, compliance violations, and reputational damage. The vulnerability's ease of exploitation without authentication increases the attack surface, making automated scanning and mass exploitation plausible. Although availability and integrity impacts are limited, the confidentiality breach alone justifies urgent remediation. Industries with high regulatory requirements or sensitive data, such as finance, healthcare, government, and technology sectors, are particularly vulnerable. The absence of known exploits currently provides a window for proactive defense, but the risk of imminent exploitation is high given the public disclosure and severity rating.

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).
