Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

XWiki Platform's Solr-based search component is affected by an information disclosure vulnerability in versions from 7.2-milestone-2 through 14.10.14, 15.5.1, and 15.6. The flaw causes the search index to expose password hashes for all users as well as any other stored credentials such as API keys that extensions may place in user-profile documents. By default all user profiles are publicly viewable, so the exposure occurs without authentication.

An unauthenticated or low-privileged attacker who can reach the Solr search endpoint can retrieve these credentials in plaintext. Successful exploitation yields the ability to obtain every user's password hash and any extension-held secrets, enabling offline cracking or direct reuse of the disclosed keys.

The GitHub Security Advisory and the project's release notes state that the issue is resolved in XWiki 14.10.15, 15.5.2, and 15.7RC1; administrators are advised to upgrade to one of these versions. No workarounds are documented.

The CVE carries a CVSS 7.5 score reflecting network-accessible, low-complexity confidentiality impact. Its EPSS score has remained near 0.51 with only minor fluctuation between the recorded peak and current values.

Vulnerability Data

XWiki Platform is a generic wiki platform. Starting in 7.2-milestone-2 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, the Solr-based search in XWiki discloses the password hashes of all users to anyone with view right on the respective user profiles.…

more

By default, all user profiles are public. This vulnerability also affects any configurations used by extensions that contain passwords like API keys that are viewable for the attacker. Normally, such passwords aren't accessible but this vulnerability would disclose them as plain text. This has been patched in XWiki 14.10.15, 15.5.2 and 15.7RC1. There are no known workarounds for this vulnerability.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-200 CWE-359

Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.

addresses: CWE-200 CWE-359

Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.

addresses: CWE-200 CWE-359

Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.

addresses: CWE-200 CWE-359

Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.

addresses: CWE-200 CWE-359

Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.

addresses: CWE-200 CWE-359

Documenting information locations and authorized users enables better protection against unauthorized exposure of sensitive data.

addresses: CWE-200 CWE-312

A data action map identifies locations where sensitive information may be exposed to unauthorized actors during processing or transfer.

addresses: CWE-200 CWE-312

The media protection policy defines requirements and procedures to prevent unauthorized disclosure or access to sensitive information on media.

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

PR.AA-05 mostly match
prevents

PR.AA-05 directly enforces least-privilege authorization that blocks most unauthorized disclosures, yet CWE-200 also arises from logging, error messages, and side-channel paths that access controls alone do not address.

PR.DS-10 mostly match
prevents

PR.DS-10 mostly prevents CWE-200 by directly eliminating unauthorized access to sensitive data-in-use, yet only partially addresses the weakness because CWE-200 spans many other exposure vectors outside runtime protection.

PR.IR-01 mostly match
prevents

PR.IR-01's segmentation/zero-trust controls largely eliminate network-level unauthorized access paths that enable exposure, yet CWE-200 spans many additional vectors (API responses, logs, app logic) that network controls alone cannot close.

PR.PS-06 mostly match
prevents

Secure SDLC practices catch most exposure flaws via design, testing and release controls, yet CWE-200 spans runtime/config issues a single development outcome cannot fully close.

PR.AA-01 partial match
prevents

PR.AA-01 supplies proper credential lifecycle controls that reduce unauthorized access paths, yet leaves many other exposure vectors (error messages, logging, side channels, etc.) unaddressed.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Restricting anonymous or unknown access and encrypting high-value information limits the exposure of sensitive data that would otherwise be obtainable by unauthorized actors.

prevents

Suppressing system details, error specifics, and previous log-on information until successful authentication reduces the information an unauthenticated attacker can gather.

prevents

By requiring owners to assign sensitivity labels and corresponding handling rules, the control ensures that information is not left unmarked and therefore reduces the chance that sensitive data will be exposed to unauthorized actors.

prevents

Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.

prevents

Secure delivery, protected storage, and confidentiality of allocation records limit exposure of authentication material to unauthorized observers.

prevents

Requiring defined procedures, assigned roles, and technical/organizational measures for handling PII reduces the chance that sensitive personal data will be exposed to unauthorized actors through inadequate handling or missing safeguards.
