### Impact An attacker who uses this vulnerability can craft a PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode filters is used on a malicious cross-reference stream. Other content streams are affected on explicit access. ### Patches This has been fixed in [pypdf==6.0.0](https://github.com/py-pdf/pypdf/releases/tag/6.0.0). ### Workarounds If you cannot upgrade yet, you might want to implement the workaround for `pypdf.filters.decompress` yourself: https://github.com/py-pdf/pypdf/blob/0dd57738bbdcdb63f0fb43d8a6b3d222b6946595/pypdf/filters.py#L72-L143 ### References This issue has been reported in #3429 and fixed in #3430.

## Summary A vulnerability was discovered in the External Secrets Operator where the `List()` calls for Kubernetes Secret and SecretStore resources performed by the `PushSecret` controller did not apply a namespace selector. This flaw allowed an attacker to use label selectors to list and read secrets/secret-stores across the cluster, bypassing intended namespace restrictions. --- ## Impact An attacker with the ability to create or update `PushSecret` resources and control `SecretStore` configurations could exploit this vulnerability to exfiltrate sensitive data from arbitrary namespaces. This could lead to full disclosure of Kubernetes secrets, including credentials, tokens, and other sensitive information stored in the cluster. --- ## Exploitability To exploit this vulnerability, an attacker must: 1. Have permissions to create or update `PushSecret` resources. 2. Control one or more `SecretStore` resources. With these conditions met, the attacker could leverage label select...

Below is a technical explanation of a newly discovered vulnerability in HTTP/2, which we refer to as “MadeYouReset.” ### MadeYouReset Vulnerability Summary The MadeYouReset DDoS vulnerability is a logical vulnerability in the HTTP/2 protocol, that uses malformed HTTP/2 control frames in order to break the max concurrent streams limit - which results in resource exhaustion and distributed denial of service. ### Mechanism The vulnerability uses malformed HTTP/2 control frames, or malformed flow, in order to make the server reset streams created by the client (using the RST_STREAM frame). The vulnerability could be triggered by several primitives, defined by the RFC of HTTP/2 (RFC 9113). The Primitives are: 1. WINDOW_UPDATE frame with an increment of 0 or an increment that makes the window exceed 2^31 - 1. (section 6.9 + 6.9.1) 2. HEADERS or DATA frames sent on a half-closed (remote) stream (which was closed using the END_STREAM flag). (note that for some implementations it's possible ...

### Background If an error occurred when resetting a user's password using the ``Forgot Password`` option in OMERO.web, the error message displayed on the Web page can disclose information about the user. ### Impact OMERO.web versions before 5.29.1. ### Patches User should upgrade to 5.29.2 or higher. ### Workarounds Disable the ``Forgot password`` option in OMERO.web using the ``omero.web.show_forgot_password`` configuration property[^1].

OS Command Injection in Olivetin 2025.4.22 Custom Themes via the ParseRequestURI function in service/internal/executor/arguments.go.

Soosyze CMS 2.0 allows brute-force login attacks via the /user/login endpoint due to missing rate-limiting and lockout mechanisms. An attacker can repeatedly submit login attempts without restrictions, potentially gaining unauthorized administrative access. This vulnerability corresponds to CWE-307: Improper Restriction of Excessive Authentication Attempts.
