A newly disclosed zero-day in GeoServer, the widely used open-source geospatial server, is already drawing exploitation attempts, according to watchTowr. The flaw is a SQL injection issue that can lead to remote code execution, and it remains unpatched, with no CVE assigned yet. It was first disclosed publicly by a researcher on August 12, and attackers commonly begin probing internet-facing servers as soon as such details appear. GeoServer instances are frequently exposed to the internet to serve mapping and location data, which makes an unpatched code-execution flaw in the platform an attractive and reachable target. Defenders should treat exposed instances as at risk until a fix ships.
Adobe released Priority 1 updates for ColdFusion and Campaign Classic, led by a critical operating-system command injection flaw in ColdFusion scored 10.0 that could give an attacker arbitrary code execution. Tracked as CVE-2026-48362, it is accompanied by an eval-injection flaw scored 9.9 and an authorization flaw that can cause a denial of service. ColdFusion application servers are a long-standing target for attackers because they are widely internet-exposed and often run with broad access. Adobe is not aware of exploitation yet but urges installation within 72 hours given the priority rating. The Campaign Classic updates apply only to on-premises and hybrid on-premises deployments.
WordPress patched a pre-authentication reflected cross-site scripting flaw in the login screen that researchers showed can chain into PHP code execution and full server takeover, naming the chain XSS2Shell. Tracked as CVE-2026-64638 and scored 8.9, the cross-site scripting bug affects all WordPress versions and needs no login to trigger. On its own it runs script in a visitor's browser, but when a logged-in administrator is lured to an attacker-controlled page, the chain can reach code execution on the server. Because WordPress runs a large share of the web, a flaw affecting every version and needing no authentication has broad reach.
Adobe patched a critical flaw in Campaign Classic, its enterprise marketing automation platform, that can let an attacker run code without any user interaction. Tracked as CVE-2026-48449 and scored 10.0, it is an incorrect authorization issue leading to arbitrary code execution in the context of the current user. The same update fixes a high-severity SQL injection flaw that allows arbitrary file reads. Affected versions are Campaign Classic v7 build 9397 and earlier on Windows and Linux, mostly on-premises and hybrid deployments, with a fix in build 9398. Adobe says it is not aware of exploitation, and separately patched eight critical flaws in Adobe Bridge.
New research shows that application security scanners embedded in the software pipeline can themselves be attacked, because analyzing a repository is not always a read-only action. Many scanners execute code or process files in ways that can be forced to run attacker content when it is handled without isolation. For example, a tool that scans cloud configuration files against a folder of custom rules can be fed a rule that is actually a malicious program, which the scanner runs when it loads it. Since scanners often hold broad access to source, secrets, and build systems, a compromised one is a strong pivot point into the wider environment.
A researcher at depthfirst published a working exploit on July 24 for a GitLab flaw patched on June 10, running commands as the git user on any self-managed 18.11.3 server that has not updated. Any authenticated user who can push to a project can trigger it: the attacker commits a crafted Jupyter notebook and opens its commit diff to leak a heap pointer, repeats until an automated probe locates libraries in memory, then fires the payload with two more notebooks. No administrator rights, runner access, or victim interaction are needed. The bug sits in the notebook renderer, which passes repository-controlled data to a parser inside a long-lived worker.
7-Zip has released version 26.02 to fix a remote code execution vulnerability that can be triggered when a user opens a specially crafted compressed file. The archiving tool is installed on a very large number of Windows systems and is routinely used to open attachments and downloads, so a flaw that fires on opening an archive is attractive to attackers who rely on phishing. There are no reports of active exploitation so far. Similar archiving tool flaws have been weaponized quickly in the past: a WinRAR vulnerability was used last year by a Russian group in phishing attacks to install malware, so patching early matters.
Security firm Mindgard disclosed an unpatched flaw in Cursor, the widely used AI code editor, that runs code automatically when a developer opens a malicious repository on Windows. When loading a project, Cursor looks for a Git binary in several places, including the workspace itself, so a file named git.exe planted in the repository root gets executed with no click, prompt, or warning, and it re-runs on a cadence while the project stays open. In a proof of concept, a renamed Windows Calculator launched on its own. Mindgard reported it in December and went public after seven months with no fix, so there is no patch and no CVE, only workarounds.
Researchers at Binarly found six flaws in U-Boot, the open-source bootloader inside routers, IoT devices, industrial systems, and the management chips of data-center servers. All six are triggered while U-Boot is still reading an untrusted firmware image, before it verifies the signature, so an attacker who supplies a malicious image can act before the trust check runs. Two of the flaws can lead to arbitrary code execution at boot, undermining the whole chain of trust, while the other four crash the device. The vulnerable code dates back to 2013, affecting many releases and vendor forks. Exploiting them does not always need physical access: a compromised management interface could push a malicious image.
Researchers at Mozilla's 0DIN found that an AI coding agent told to clone and set up a seemingly harmless GitHub repository can be tricked into running malware that stays invisible to security scanners, the agent itself, and human reviewers. The trick is that nothing malicious sits in the repository's files. Instead, a routine-looking setup command runs a script that fetches a value hidden in a DNS TXT record and executes it as a shell command, pulling down and running an attacker's payload like a reverse shell. Because the payload lives outside the repo and arrives over DNS at setup time, code review and static scanning see nothing wrong.
