CVE-2026-56308 HIGH PATCH This Week

Account takeover in Capgo before 12.128.2 arises because the email-change endpoint performs no current-password re-authentication and no verification of the existing email address, letting an attacker who already holds a valid session cookie or an authenticated browser silently repoint the account email. By seizing the recovery address, the attacker captures password-reset flows and sidesteps multi-factor authentication, converting a hijacked session into durable full account control. There is no public exploit identified at time of analysis, but the flaw is vendor-confirmed via GitHub Security Advisory GHSA-9px4-w25f-mvm4 and reported by VulnCheck.

CVE-2026-15479 MEDIUM POC This Month

Unauthenticated remote password modification on H3C NX15 V100R017 routers allows any network-reachable attacker to overwrite the administrator password via the change_passwd function at the /api/login/modify endpoint, effectively seizing full administrative control of the device. The vulnerability stems from a missing authentication or authorization check on the password modification API (CWE-640), meaning no credentials or session token are required to invoke it. A public proof-of-concept exploit is available on GitHub, and no vendor patch has been identified at time of analysis.

CVE-2026-15155 HIGH This Week

Authenticated account takeover in the Essential Addons for Elementor WordPress plugin (versions ≤ 6.6.10) lets a Contributor-or-above user inject a Bcc header into WordPress's administrator password-reset email via the plugin's Login/Register widget, capturing a valid admin reset link and seizing the site. The flaw stems from an email-header (CRLF) injection where the allowed-values check is enforced only in the browser editor, not server-side. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV; the vendor fixed it in version 6.6.11.

Account takeover in the SureCart e-commerce plugin for WordPress (versions ≤ 4.2.3) lets unauthenticated attackers overwrite the email address of any WordPress user linked to a SureCart customer record during webhook-driven customer profile synchronization. Because the plugin does not verify the requester's identity before applying the update, an attacker who knows a victim's customer ID - including that of an administrator - can change the account email, trigger a password reset, and seize the account. No public exploit is identified at time of analysis, but the flaw was reported by Wordfence and carries a CVSS of 8.1.

CVE-2026-55207 HIGH PATCH This Week

Full admin account takeover in Pimcore (Studio backend) before 2025.4.6 and 2026.1.6 lets an unauthenticated attacker who knows a valid admin username hijack that account by submitting a password-reset request with an attacker-controlled resetPasswordUrl; the server appends a genuine recovery token to that URL and emails it to the victim, so a single victim click leaks the token to the attacker, who authenticates via POST /pimcore-studio/api/login/token with full admin rights and bypasses 2FA. GitHub advisory GHSA-h854-c3m3-mh5v classifies this as an authentication bypass (CWE-640). No public exploit identified at time of analysis, and it is not listed in CISA KEV; EPSS was not provided.

CVE-2026-13019 CRITICAL PATCH Act Now

Missing authentication in Esri Portal for ArcGIS 12.1 and earlier (Windows, Linux, and Kubernetes deployments) exposes a critical API endpoint that a remote, unauthenticated attacker can reach directly, bypassing access controls to interact with functionality that should require an authenticated session. Esri rates this critical (CVSS 9.8) and disclosed it in its June 2026 ArcGIS security bulletin; no public exploit identified at time of analysis and it is not listed in CISA KEV. Because the exposed function is an administrative/portal API reachable over the network with no credentials, successful access could lead to disclosure or manipulation of portal content and configuration.

Account takeover in Esri Portal for ArcGIS 12.1 and earlier (Windows, Linux, and Kubernetes) stems from a weak forgotten-password recovery mechanism (CWE-640) that a remote, unauthenticated attacker can manipulate to assume ownership of another user's account. The flaw carries a CVSS 9.8 rating because it is network-reachable with no authentication or user interaction, yielding full compromise of confidentiality, integrity, and availability of the targeted account. There is no public exploit identified at time of analysis and EPSS is low (0.22%, 13th percentile), and CISA's SSVC framework records exploitation as none, indicating no observed in-the-wild activity despite the critical score.

CVE-2026-34198 MEDIUM PATCH This Month

Password reset poisoning in Coolify prior to 4.0.0-beta.471 enables unauthenticated account takeover by injecting a forged X-Forwarded-Host header during a password reset request. Two compounding middleware failures make this possible: TrustProxies trusts all proxy sources unconditionally, and TrustHosts is rendered inoperable by a circular caching dependency, meaning the Host header is never validated. The reset URL is generated from the spoofed request host, so the victim's reset token is delivered to an attacker-controlled domain. No public exploit is identified at time of analysis, but the attack is low-friction and the fix is confirmed in version 4.0.0-beta.471.

CVE-2026-53646 HIGH This Week

Account takeover in FOSSBilling 0.5.6 through 0.7.2 arises because the reset_password guest API endpoint reuses an existing, unexpired ClientPasswordReset token rather than rotating it on each request. An attacker who has captured a victim's earlier reset link retains a valid path to hijack the account even after the victim requests a fresh reset, since the original token is never invalidated and its 15-minute window is anchored to the first request. No public exploit is identified at time of analysis, and the CVSS 4.0 score is 7.7 (High); version 0.8.0 fixes the flaw.

Remote code execution is claimed in DokuWiki 2025-05-14b "Librarian" (build 56.2) via the register function in inc/auth.php, which security intelligence maps to CWE-640 (weak password-recovery mechanism) - a mismatch that suggests account-takeover-to-code-execution rather than a direct memory-corruption RCE. The CVSS 3.1 score of 9.8 (network, no authentication, no user interaction) implies any internet-facing DokuWiki instance is at risk, and publicly available exploit code exists (a public gist proof-of-concept plus SSVC 'poc' exploitation status), though EPSS remains low at 0.26% (17th percentile), indicating no observed mass exploitation yet. Reported by MITRE and tracked as ENISA EUVD-2026-40863, it is tagged PHP/RCE but is not listed in CISA KEV.
