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 2026-10-26.

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 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

European organizations should immediately upgrade run-llama/llama_index to version 0.12.41 or later, where the vulnerability is fixed. Until the upgrade is applied, organizations should implement strict input validation and sanitization on all user-supplied file paths to prevent path traversal sequences. Employ application-layer firewalls or web application firewalls (WAFs) with custom rules to detect and block suspicious path traversal patterns in requests. Restrict file system permissions so that the application process has access only to necessary directories and files, minimizing exposure if exploitation occurs. Conduct thorough code reviews and static analysis on any custom code interacting with file paths to ensure no similar vulnerabilities exist. Monitor logs for unusual file access patterns or errors that could indicate attempted exploitation. Finally, ensure network segmentation and limit exposure of vulnerable services to trusted internal networks when possible to reduce attack surface.

Description

A path traversal vulnerability exists in run-llama/llama_index versions 0.12.27 through 0.12.40, specifically within the `encode_image` function in `generic_utils.py`. This vulnerability allows an attacker to manipulate the `image_path` input to read arbitrary files on the server, including sensitive system files. The issue arises due to improper validation or sanitization of the file path, enabling path traversal sequences to access files outside the intended directory. The vulnerability is fixed in version 0.12.41.

Impact

For European organizations using the run-llama/llama_index library versions 0.12.27 through 0.12.40, this vulnerability poses a serious risk to the confidentiality of sensitive data. Attackers exploiting this flaw can read arbitrary files on affected servers, potentially exposing credentials, configuration files, intellectual property, or personal data protected under GDPR. This could lead to data breaches, regulatory fines, reputational damage, and loss of customer trust. Since the vulnerability does not affect integrity or availability, the primary concern is unauthorized data disclosure. Organizations relying on run-llama for AI or machine learning workloads that process images or files are particularly at risk. The vulnerability's network accessibility and lack of authentication requirements increase the likelihood of exploitation, especially in internet-facing deployments or environments with insufficient network segmentation. Given the sensitivity of data handled by many European enterprises and strict data protection regulations, the impact could be substantial if exploited.

CWE-29Path Traversal: '\..\filename' (opens in a new tab)
Variant weakness
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that 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.
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).
