The interface key of the blog program was exploited to poison more than seven hundred pages, how to separate the prevention of hosting environment and program vulnerabilities
The blog program's API key was exploited and poisoned over seven hundred pages - To answer how to separate the prevention of hosting environment and program vulnerabilities, let's first look at what problems were encountered in the two layers of this Ghost event.The security research disclosure reveals that attackers exploited the issue numbered CVE-2026-26980 to steal the site's Admin API Keys (management interface keys), followed by injecting诱ing content into the page, more than seven hundred domain names were polluted, and the injected pages were引导visitors to execute malicious operations using the ClickFix method.There are both self-built and hosted sites affected, and the actions taken for the two types of readers are not the same.
At which layer does the poisoning occur
This event is not about modifying the database content, but the rendering layer that visitors actually see: injection occurs in the page output path. The admin may see everything normal in the editing interface behind the scenes, but the crawlers and visitors get HTML with additional content. This is the reason for the concealment of poison type attacks - the site owner himself is browsing safely, while traffic and reputation are collapsing from the search and sharing entry. The investigation must be done from an external perspective: use clean network requests to the homepage and high-traffic articles, compare the additional scripts and jumps in the source code, rather than just looking at the background.
Two paths of key leakage
The first path directly exploits program vulnerabilities: CVE-2026-26980. Such interface layer defects allow attackers to read or use management-level credentials without obtaining account passwords, and the only defense measures left are version repair and interface exposure surface convergence.The second path is a configuration leak: keys are hard-coded in templates, permissions are given to the entire site, and old keys are never revoked. Such issues do not involve any vulnerability numbers, but they directly escalate the first available flaw to full-site write permission.Different strategies for two paths: the former monitors announcements and quickly upgrades; the latter relies on discipline - the key is only given to 'this site, this use', and it is rotated after use.
Division of labor between hosting and self-built defense lines
The hosting environment assigns the responsibility of the system layer (patches, firewalls, machine isolation) to the platform provider, while the site owner's responsibility is condensed to application configuration and credential management; in a self-built environment, both layers are under the control of the owner themselves. The judgment basis is simple: after an incident, whoever has root access, their list should include this item. For hosted sites, you need to ask the platform three things - whether the vulnerability repair has taken effect in your instance, whether you can get file-level alerts, and whether the recovery can roll back to a specified time point; for self-built sites, these three things become the owner's operational tasks.
Implementation list: backup rollback and interface authentication
No matter what kind of environment, the ability to recover comes first: AnQiCMS makes the backup of data and static files a site function, the standard action for dealing with poisoning events is to roll back the entire site from the backup of 'known clean points', rather than deleting the injected code one by one - the attacker often leaves more than one place.Roll back and add two layers: First, tighten the authorization boundary between the interface and login, built-in JWT authentication to control the session, and issue interface credentials with the minimum permissions to the outside and rotate them regularly;Add monitoring to the rendering layer, regularly grab the source code of the homepage to perform baseline comparison, and alert in time for any extra external links and scripts. The output layer mechanism for preventing scraping interference codes also has a side effect at this point: tools for moving and injecting work according to the general parser, and adding validation anchors to the output structure makes it easier to compare exceptions.
Common questions
Question: Do blogs hosted on the platform need to fix CVE themselves?Answer: The repair action is usually performed by the platform, but the site owner needs to confirm that their instance is effective and immediately rotate the management interface key - plug the hole of the platform supplement program, and supplement the account of your credentials.
Question: Is it okay to just delete the injected code?Answer: The risk lies in the residue. Injected scripts are often deployed in multiple points and scheduled tasks recur, so it is more reliable to roll back the entire clean backup and then compare it than to clean up piece by piece.
Question: How can a self-built site use Anqi CMS to prevent this chain?Answer: Three actions - enable data and static file backup and practice recovery, tighten the session with built-in JWT authentication, and issue credentials only for the use of a single site and change them in a timely manner.
