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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

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 12 Nov 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 pgEdge RAG Server to version 2.0.0 or later, where the vulnerability is fixed by preventing provider error messages from reaching API clients. After upgrading, rotate any LLM provider credentials that were configured on affected versions if the query endpoint was reachable by untrusted parties, especially if authentication failures occurred. As a temporary workaround, place the server behind a proxy that rewrites 5xx response bodies or terminates provider errors before they reach the API surface, or ensure provider credentials remain valid to avoid authentication failures. However, these workarounds do not fix the underlying issue and are not substitutes for upgrading.

Description

pgEdge RAG Server versions 1.0.0 and earlier expose part of the configured LLM provider API key through error messages returned by the query API. An unauthenticated remote attacker can trigger provider authentication failures that cause the server to relay upstream provider error messages containing partially masked credentials. This disclosure affects third-party provider accounts and has a scope change impact. The issue is fixed in version 2.0.0 by preventing provider error text from reaching API clients. Users should upgrade and rotate any exposed credentials.

Impact

An unauthenticated attacker can obtain partial fragments of the LLM provider API key configured on the server by causing authentication failures and reading the resulting error messages. This disclosure affects the third-party provider account credentials, not the pgEdge software itself, resulting in a scope change. The partial credential exposure could facilitate unauthorized access to the third-party provider services if combined with other information. There is no indication of direct impact on the pgEdge server's integrity or availability.

Summary

The vulnerability in pgEdge RAG Server (CVE-2026-125326) allows unauthenticated remote callers to read fragments of the operator's configured LLM provider API key via the query API error messages. The server relays the upstream provider's error message directly to the client, which includes a partially masked form of the rejected credential. This occurs because the error handling code returns the provider's error message or the entire response body when pipeline execution fails. The affected versions include 1.0.0 and all earlier pre-releases with an unauthenticated query endpoint. The fix in version 2.0.0 introduces internal error handling to prevent provider error text from being exposed. Credential rotation is recommended after upgrading due to prior exposure.

CWE-209Generation of Error Message Containing Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product generates an error message that includes sensitive information about its environment, users, or associated data.
Implementation
Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended).
Implementation
Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
Implementation · Attack Surface Reduction
Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
