CVE-2026-34309 Apr 21, 20:35 HIGH This Week

Broad data compromise in Oracle PeopleSoft Enterprise PeopleTools 8.61 through 8.62 allows a low-privileged, network-adjacent attacker to reach any data the platform can access. The flaw sits in the Security component and is characterized by improper access control (CWE-284, tagged as Authentication Bypass), letting an authenticated-but-unprivileged user read, create, delete, or modify critical data across the deployment. There is no public exploit identified at time of analysis, EPSS risk is very low (0.03%), and it is not on CISA KEV.

Password reset poisoning in LinkAce (self-hosted link archive by Kovah) before 2.5.4 allows a remote attacker to hijack accounts by injecting a malicious host into reset URLs. Because the app trusts the X-Forwarded-Host header when building password reset links, an attacker who triggers a reset for a victim can cause the emailed link to point to an attacker-controlled domain; if the victim clicks it, the valid reset token leaks to the attacker, enabling full account takeover. No public exploit identified at time of analysis, and EPSS is very low (0.03%), consistent with SSVC exploitation status of 'none'.

CSS injection in FreeScout mailbox signatures enables CSRF token exfiltration and privilege escalation from authenticated agents to administrators. The vulnerability exists in FreeScout versions prior to 1.8.213 where incomplete input sanitization fails to strip <style> tags from mailbox signature fields. Attackers with mailbox configuration access leverage CSS attribute selectors to steal CSRF tokens from viewing users, then perform arbitrary state-changing actions including admin account creation. EPSS data not available; no confirmed active exploitation (CISA KEV absent). Vendor patch released in version 1.8.213 with complete fix addressing previous incomplete remediation (GHSA-jqjf-f566-485j).

OS command injection in GitHub Enterprise Server (all releases prior to 3.21) lets an authenticated Management Console administrator run arbitrary shell commands on the underlying appliance by embedding shell metacharacters in proxy configuration fields such as http_proxy. The flaw was reported through the GitHub Bug Bounty program and there is no public exploit identified at time of analysis; EPSS is negligible (0.01%, 3rd percentile) and CISA SSVC rates exploitation as none. Because it requires high-privilege console access, it is primarily a privilege-boundary escape from Management Console admin to full OS-level control rather than a remotely reachable pre-auth issue.

CVE-2026-22016 Apr 21, 20:35 HIGH PATCH This Week

Unauthorized data disclosure in Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition arises from a flaw in the JAXP (Java API for XML Processing) component, allowing an unauthenticated remote attacker to read critical or all accessible data across affected JDK 8, 11, 17, 21, 25, and 26 builds. The confidentiality-only issue (CVSS 7.5, C:H/I:N/A:N) is easily exploitable over multiple network protocols, including via web services that pass attacker-supplied data into JAXP APIs, and also affects sandboxed Java Web Start/applet deployments running untrusted code. There is no public exploit identified at time of analysis and EPSS is very low (0.03%, 9th percentile), consistent with the SSVC exploitation status of 'none'.

CVE-2026-6782 Apr 21, 12:41 HIGH PATCH This Week

Unauthenticated remote attackers can obtain sensitive information from Firefox's IP Protection component prior to version 150 via network-accessible requests with low attack complexity. The vulnerability leaks confidential data (CVSS:C=High) without requiring user interaction or special privileges, affecting all Firefox installations below version 150. Mozilla has released a vendor-confirmed patch in Firefox 150. No active exploitation (CISA KEV) or public exploit code identified at time of analysis, though CVSS vector indicates trivial exploitation conditions (AV:N/AC:L/PR:N/UI:N).
