NVD Disruptions Force Security Teams to Diversify Vulnerability Intelligence Sources
The vulnerability management process begins with reliable information about which vulnerabilities exist. Over the past couple of years the ecosystem of vulnerability data sources has experienced a genuine earthquake. What once seemed permanent and unshakable — a single CVE database carefully enriched by the American NVD — has suddenly become unstable. This article examines where to obtain vulnerability data today and why depending on one source has become risky.
Primary Vulnerability Data Sources for the Russian Market
BDU FSTEC (bdu.fstec.ru) is the Russian national threat database. Its advantages include orientation toward the Russian market and legislation, official state-recognized data, detailed descriptions with remediation recommendations, and coverage of domestic software that may be absent from Western databases. As of August 2026 the database contains more than 92 thousand vulnerabilities. Entries use identifiers in the format BDU:2024-01398. Users can find descriptions, consequences, and mitigation guidance. FSTEC also maintains a separate section on the most dangerous trending vulnerabilities, serving as the Russian analogue of the catalog of exploited vulnerabilities.
NVD (nvd.nist.gov), maintained by NIST, is the American national vulnerability database. It offers broad coverage, detailed descriptions, and mappings to CVSS and CPE. However, NVD has been at the center of the main drama of recent years, which is discussed below.
The CVE database maintained by MITRE is the international registry of vulnerability identifiers. CVE serves as the global identification standard; the same identifier CVE-2021-44228 (Log4Shell) is recognized worldwide. Both NVD and BDU, as well as vendor products, rely on CVE records.
Vendor security bulletins from software manufacturers such as Microsoft, Cisco, Astra Group, Positive Technologies and others frequently provide the earliest and most accurate information.

WordPress Click2Shell Flaw Chain Lets Attackers Achieve RCE via Single Admin Click
Researchers discovered a chain of vulnerabilities in WordPress core named Click2Shell that enables remote code execution without attacker authentication. The attack requires only that a logged-in administrator opens a specially crafted preview link, after which the interface automatically installs a malicious theme. Researcher Paulos Yibelo from pwn.ai found that inconsistent parameter handling between the theme directory API and browser JavaScript allowed the crafted URL to trigger installation without user interaction. A second vulnerable component, the Mobile Repair Zone 2.5.4 theme from the official directory, was used to load arbitrary PHP code and abuse an insecure AJAX handler for plugin installation. Successful exploitation grants full access to wp-config.php, database credentials, file modification rights, and the ability to create new administrators. WordPress addressed the issue in version 6.7.1 and backported fixes to supported branches, while the constant DISALLOW_FILE_MODS offers temporary mitigation by blocking theme and plugin changes.
Cache Key Injection Flaw in Nginx Configurations Allows Access Bypass, Data Disclosure and Cached Denial of Service
Security researcher Alex Brumen from YesWeHack has detailed a Cache Key Injection attack vector that exploits poorly constructed cache keys in Nginx. The issue arises when administrators concatenate variable-length values without delimiters, such as $scheme$host$request_uri$http_accept, allowing different requests to produce identical cache keys. Attackers can poison the cache with 404 responses to deliver CPDoS, expose restricted pages like /admin by manipulating path components, or even achieve stored XSS by colliding HTTP and HTTPS responses. The technique can also bypass Cloudflare protection when the Authorization header routes requests directly to the vulnerable Nginx cache. Mitigation requires using explicit delimiters or structured encoding in cache keys, validating the Host header, enforcing HTTPS redirects, and avoiding caching of authenticated requests.
Click2Shell Flaw in WordPress Core Enables Remote Code Execution via Single Malicious Link
Researchers at pwn.ai have disclosed Click2Shell, a vulnerability in the WordPress core that allows an attacker to install a malicious theme and achieve remote code execution simply by tricking an authenticated administrator into opening a crafted link. The isolated flaw carries a CVSS score of 7.1, but the full attack chain reaches 9.6. The issue stems from an interpretation mismatch between the WordPress.org theme directory and the administrator browser, causing the browser to automatically trigger the install button without any user confirmation or password prompt. Affected versions start from 6.0 and run up to but not including 7.1.1. The vulnerability has been fixed in WordPress 7.1.1 with backported patches released for all supported branches down to version 4.7. No exploitation in the wild had been observed at the time of disclosure, yet the low barrier of convincing an admin to click a link makes prompt patching essential.
CISA Adds Three Actively Exploited Linux Kernel Vulnerabilities to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency has added three vulnerabilities affecting the Linux Kernel to its Known Exploited Vulnerabilities catalog. The flaws, identified as CVE-2025-39682, CVE-2026-53266, and CVE-2025-39964, are confirmed to be under active exploitation in the wild. CISA is directing all federal agencies to apply patches immediately and to search for indicators of compromise. The vulnerabilities impact the kernel's kTLS TLS processing, the ebtables network bridge component, and the AF_ALG cryptographic interface. Each issue can lead to memory corruption or inconsistent internal state that attackers may leverage for privilege escalation or remote code execution.
