PhpSpreadsheet is a pure PHP library for reading and writing spreadsheet files. From 3.3.0 until 3.10.8 and 5.10.0, Reader\Xml passes stored SpreadsheetML XML through XmlScanner::scan in Xml::canRead and Xml::trySimpleXMLLoadStringPrivate, while Xml::unentity decodes numeric entities only after each DOCTYPE pattern check. A double-encoded less-than character is reduced by the first callback to another encoded character and by the second callback to a literal less-than sign, so SimpleXML receives an unchecked DOCTYPE and entity declaration. Processing attacker-controlled SpreadsheetML XML can cause entity-expansion denial of service and can permit local file access or SSRF on PHP before 8.0 or when LIBXML_NOENT is enabled. This issue is fixed in versions 3.10.8 and 5.10.0.
CVE-2026-114611 is a critical vulnerability in schorschii OCO-Server versions prior to 1.2.3 involving improper certificate validation in the Apple MDM enrollment endpoint. The vulnerability allows an attacker to forge enrollment requests using arbitrary self-signed certificates, bypassing proper certificate chain validation. This leads to issuance of a valid MDM identity certificate for a victim device, enabling device-record hijacking and impersonation of the victim device in MDM communications. Version 1.2.3 addresses this issue.
PhpSpreadsheet versions prior to 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0 contain a vulnerability in the Ods::processTableRow function. This vulnerability allows an attacker to specify an unbounded number of repeated rows in an ODS spreadsheet file, causing uncontrolled resource consumption. The issue can lead to substantial CPU and memory usage, potentially terminating the PHP worker process. This vulnerability has been fixed in the stated versions.
CVE-2026-93336 is a missing authorization vulnerability in Canonical Juju versions 4.0 through 4.0.15. It allows a controller-authenticated principal, such as a unit agent or a user with only login permission, to read any application's charm resource across any model. This includes sensitive data like container-registry credentials, accessible via a crafted request specifying an arbitrary unit.
PhpSpreadsheet is a pure PHP library for reading and writing spreadsheet files. Prior to 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0, XmlScanner::scan in src/PhpSpreadsheet/Reader/Security/XmlScanner.php uses a DOCTYPE detection pattern that accounts for NUL-byte interleaving but not ISO-2022 escape sequences in XLSX XML parts. The escape sequences prevent the scanner from matching the declaration, and XML charset normalization then removes the escape bytes before parsing, exposing a valid DOCTYPE and entity definitions. Processing an attacker-controlled XLSX can therefore cause entity-expansion denial of service on supported PHP versions and can permit local file access or SSRF on PHP before 8.0 or when LIBXML_NOENT is enabled. This issue is fixed in versions 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0.
CVE-2026-108360 is an authorization vulnerability in PHPOffice PhpSpreadsheet affecting versions prior to 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0. The issue arises when external image URLs are validated only initially, allowing a permitted image host to redirect the server to internal addresses, causing blind GET requests. Although the response body is not exposed to attackers, internal endpoints and cloud metadata services may be accessed. This vulnerability has a medium severity rating with a CVSS score of 6.4 and has been fixed in the specified versions.
CVE-2026-54238 is a vulnerability in Supabase Realtime prior to version 2.103.1 where expired JWT tokens with the exp claim encoded as a JSON string are incorrectly accepted by REST broadcast endpoints. This allows an unauthenticated attacker to broadcast realtime messages to subscribers. The issue is patched in version 2.103.1.
A resource exhaustion vulnerability exists in the py-pdf fpdf2 library versions 2.5.0 through 2.8.7. The issue arises from nested SVG <use> references that cause exponential growth in memory and CPU usage during PDF generation, potentially leading to MemoryError and job failures. This vulnerability is fixed in version 2.8.8.
fpdf2, a Python PDF creation library, has a Server-Side Request Forgery (SSRF) vulnerability in versions prior to 2.8.8. The shared image loader automatically dereferences attacker-controlled HTTP(S) URLs and raw local paths supplied through various image input methods, potentially causing outbound requests to attacker-chosen services or local file reads if the content is a valid image or SVG. The issue is fixed in version 2.8.8.
Arista Networks patched a critical zero-day vulnerability (CVE-2026-114625) in VeloCloud Orchestrator (VCO) On-Prem deployments. The flaw allows authenticated users with basic privileges to escalate to operator-level privileges via low-complexity SQL injection attacks without user interaction. This enables access to internal functionality not intended for remote access, potentially compromising the confidentiality, integrity, and availability of the orchestrator and managed data. Hosted VCO deployments running versions 5.2.3.18 or later, 6.1.3.10 or later, and 6.4.2.12 or later have been patched. Until patches are applied, Arista recommends restricting VCO web interface access, monitoring for suspicious activity, and blocking known malicious IP addresses involved in ongoing attacks.
CVE-2026-54532 affects CloudPirates Open Source Helm Charts, where a pull_request_target GitHub Actions workflow was vulnerable to cache poisoning and OIDC token theft. The workflow checked out forked code using untrusted references, allowing attacker-controlled code to access repository secrets and tokens. The shared Actions cache could be poisoned by this workflow, enabling malicious code execution in subsequent release or publish workflows. This vulnerability has been patched in commit 271d415.
Eight intermediate certificate authority (CA) private keys belonging to Indian CA eMudhra Limited were compromised due to insufficient randomness in the certificate generation process. This cryptographic weakness allows attackers to derive private keys from public certificates, enabling unauthorized TLS certificate signing and potential man-in-the-middle (MitM) attacks. Major browser and OS vendors have revoked trust in these intermediates, and eMudhra has revoked the eight compromised certificates. Organizations are advised to audit PKI assets, reissue certificates from trusted CAs, enforce strict revocation checking, and update trust stores to mitigate risk. Palo Alto Networks provides solutions and guidance to assist with managing this incident and preventing exploitation.
CVE-2026-78667 is a denial of service vulnerability in Golang's HTTP file serving functions triggered by parsing Range headers with many small ranges. This causes excessive CPU consumption and can exhaust server resources, impacting availability without affecting confidentiality or integrity. Red Hat has issued a security advisory with an update to address this issue in their golang packages for Red Hat Enterprise Linux 10. The vulnerability has a CVSS score of 7.5, indicating medium severity. No known exploits are reported in the wild.
This analysis from Unit 42 explores the evolving threat landscape targeting OAuth authorization tokens. Attackers increasingly steal OAuth tokens rather than credentials, enabling them to bypass MFA, survive password resets, and maintain persistent access. Key vulnerabilities include Cross-User OAuth Session Fixation, Cross-Tenant Client ID Confusion, and Cross-Connector OAuth Account Takeover, especially in OAuth-as-a-service environments. These attacks allow account takeover, lateral movement, and data exfiltration without triggering traditional credential alerts. Mitigations include disabling end-user app consent for vague apps, enforcing admin-only approval workflows, monitoring authorization code clipboard events, and auditing redirect URIs. OAuth security depends heavily on the identity provider's protections, which vary widely.
Incorrect authorization checks in Amazon Athena engine version 3 query processing could have allowed an authenticated user to read AWS account identifiers and SQL statement text query metadata from other AWS accounts. Query results, and data stored in Amazon S3 or other data sources, were not accessible through this issue.
AWS remediated the issue on October 7, 2026. No customer action is required.
Pylint versions from 0.15.2 up to but not including 4.0.9 have a vulnerability where module statistics are stored in predictable cache files and loaded using pickle.load. An attacker with write access to the cache directory can replace these files with malicious serialized data, leading to arbitrary code execution with the privileges of the user running Pylint. The default per-user cache is typically not writable by others. This issue is fixed in version 4.0.9.
draw.io Desktop versions prior to 31.4.4 contain a path traversal vulnerability allowing arbitrary local file disclosure. The issue arises because several Electron main process read-side IPC handlers operate on user-chosen filesystem paths without proper authorization checks, leading to a read/write authorization asymmetry. This vulnerability is fixed in version 31.4.4.
